![]() Node Version Manager, more commonly called nvm, is the most popular way to install multiple versions of Node.js. ![]() You will likely need to switch between multiple versions of Node.js based on the needs of different projects you're working on. We recommend using a version manager as versions change very quickly. Install nvm, node.js, and npmīesides choosing whether to install on Windows or WSL, there are additional choices to make when installing Node.js. Install Windows Terminal using the Microsoft Store: By installing via the store, updates are handled automatically. You can also create custom key bindings (shortcut keys for opening or closing tabs, copy+paste, etc.), use the search feature, customize your terminal with themes (color schemes, font styles and sizes, background image/blur/transparency), and more. Windows Terminal is an improved command line shell that allows you to run multiple tabs so that you can quickly switch between Linux command lines, Windows Command Prompt, PowerShell, Azure CLI, or whatever you prefer to use. To update your distribution, use the command: sudo apt update & sudo apt upgrade. Windows doesn't automatically handle this update. We recommend updating your Linux distribution regularly, including immediately after you install, to ensure you have the most recent packages. ![]() Once you have installed WSL 2 and a Linux distribution, open the Linux distribution (it can be found in your Windows start menu) and check the version and codename using the command: lsb_release -dc. These steps will include choosing a Linux distribution (for example, Ubuntu). To enable and install WSL 2, follow the steps in the WSL install documentation. ![]() WSL 2 is the most recent version available for Windows and we recommend it for professional Node.js development workflows. This recommendation also applies if you plan to use a Windows Server production environment. If you are new to developing with Node.js and want to get up and running quickly so that you can learn, install Node.js on Windows. ![]()

![]() ![]() This cut is made just before the second force along the beam. The equation for this part of our bending moment diagram is: So as we move further from the force, the magnitude of the bending moment will increase. Now as you recall, a bending moment is simply the force x distance. In this case, we have a 10kN force in the upward direction. So, when we cut the beam, we only consider the forces that are applied to the left of our cut. Make a “cut” just after the first reaction of the beam. Starting at x = 0 we will move across the beam and calculate the bending moment at each point. To calculate the bending moment of a beam, we must work in the same way we did for the Shear Force Diagram. From left to right, make “cuts” before and after each reaction/load Finally calculating the moments can be done in the following steps:Ģ. Once you have the reactions, draw your Free Body Diagram and Shear Force Diagram underneath the beam. If you’re not sure how to determine the reactions at the supports – please see this tutorial first. ![]() Calculate reactions at supports and draw Free Body Diagram (FBD) With the definitions out of the way, let’s look at the steps to calculate a bending moment diagram:įree Beam Calculator Calculating Bending Moment Diagram by Hand 1. It is important to remember two things when calculating bending moments (1) the standard units are Nm and (2) clockwise bending is taken as negative. A Bending Moment is simply the bend that occurs in a beam due to a moment. It is calculated as the perpendicular force multiplied by the distance from the point. It’s good to note early, that the Sk圜iv Beam software can display these hand calculations instantly and automatically! We will follow todays tutorial with an example taken directly from the Hand Calculation Module in Sk圜iv Beam.įirstly, what is a bending moment? A moment is a rotational force that occurs when a force is applied perpendicularly to a point at a given distance away from that point. The ability to calculate the moment of a beam is a very common practice for structural engineers and often comes up in college and high school exams. Study this method as it is very versatile (and can be adapted to many different types of problems.

Scroll to the bottom for more advice on how to get the most out of your stud finder. Take everything with a grain of salt, and use the stud finder in conjunction with the placement of electrical and plumbing fixtures to figure things out. While you may get definitive results in one case, you could be left scratching your head in another. Stud finders have their jobs cut out for them, given the many variables in wall materials and construction. If you plan on hanging heavier items or anything that’ll bear weight, like a shelf or a bike rack, you might want to get an electronic stud finder to make sure you’re on target.Ĭlockwise, from left: detecting a ferrous object-black pipe-in our test wall finding a stud’s center setting deep scan mode. The most advanced stud finders use technology like ground-penetrating radar, which uses radar pulses to create a subsurface image.įor most occasional home uses, like hanging pictures or bathroom mirrors, a magnetic stud finder will do the trick. ![]() Some also identify metal pipes or electrical wires. When the signal changes, the stud finder beeps or flashes to let you know it’s found a stud. Most electronic stud finders work by sending out a signal from a sensor inside, then reading the signal that bounces back. In commercial construction, where metal studs are standard, you may find magnetic stud finders more useful. If the builder missed the stud, so will the magnetic stud finder. Magnetic stud finders aren’t always the most accurate, though-they rely on the fastener actually being driven into the stud. We tested several options to find the best stud finders for home and commercial use, whether you just need a hand hanging up your new shelves or you’re hoping to avoid damage while you work within the drywall. To test all the features, we put a selection of stud finders through their paces on a wall of our own making and walls in real homes. That doesn’t mean that stud finders work like X-ray vision, though-there’s a lot going on in walls, and it can be hard, despite advances in tech, for any device to determine what’s a pipe and what’s a wire, for instance. This can help make sure you don’t hit a pipe or wire when hanging something up-a mistake that can quickly become an expensive one. Some stud finders have other features, too, like deep scanning and AC wire detection. ![]() Studs-the wooden or metal beams that your drywall is attached to-are the most sturdy place to sink weight-bearing anchors into drywall to ensure your wall hangings don’t fall. Knowing where your studs are is crucial for hanging up heavy items, like mirrors or mounts for flat-screen TVs. A stud finder is good for, well, finding studs you can’t see. ![]() ![]() ![]() Perhaps the greatest utility that the TIMI score has to offer is its ability to guide the management of patients presenting with signs of unstable angina/non-ST elevated myocardial infarctions (UA/NSTEMI). Nursing, Allied Health, and Interprofessional Team Interventions Recent studies have also shown that the amplitude of ST-segment elevation or depression and the degree of cardiac biomarker elevation (troponin T/I) can both be independent factors that could point toward initiating early invasive cardiac procedures. Studies have also noted that of the seven factors that contribute to the TIMI risk score, history of coronary artery disease, age greater than or equal to 65, and deviations in ST-segment on initial EKG’s were more strongly associated with adverse cardiac events as compared to the other factors. The study found that patients who had a risk score of 5 to 7 were significantly more likely to have severe culprit stenosis, multivessel disease, left main coronary artery disease, or visible thrombus compared to those who were in the low-risk score category. The TIMI risk score was found to be predictive of the severity of the vascular disease, making it a powerful tool to predict the potential blood vessels of coronary circulation that could be involved.Ī sub-study of PRISM-PLUS compared TIMI risk scores to findings on coronary angiography. However, other studies have shown that the TIMI, CADILLAC, and PAMI scores were superior to the GRACE score in determining high-risk patients in need of cardiac catheterization. Studies have shown that the CADILLAC score was more helpful in predicting six-month to one-year outcomes. Issues of ConcernĪpart from the TIMI risk score, there are other predictive tools such as the GRACE, PAMI, and CADILLAC risk scores that provide insight into management and mortality risk assessment. Studies have shown that the TIMI risk score is far superior in providing diagnostic evidence for acute coronary syndrome (ACS) compared to history, physical examination, EKG’s, or biomolecular cardiac markers alone. Scores from 3-5 are considered intermediate risk. Scores ranging from 0-2 constitute a low risk. The following represents scores paired with the percent risk of mortality, new/recurrent MI, or severe ischemia requiring further invasive cardiac intervention. A higher score implies a higher likelihood of adverse cardiac events and/or risk of mortality. If present, each factor contributes a value of one point toward the TIMI risk score, making it a simple tool that does not require differential weights for each factor. Elevated serum cardiac markers of necrosis.ST-segment deviations greater than or equal to 0.05 mV on initial ECG at admission.Presence of greater than or equal to 2 episodes of angina 24 hours before the presentation.Previous history of coronary stenosis of 50% or more.Presence of at least three risk factors for coronary artery disease (i.e., diabetes mellitus, hypertension, hyperlipidemia, smoking, family history).According to several trials, notably TIMI 11B and ESSENCE, seven factors help assess the mortality risk and risk of other adverse cardiac events, as listed below. The thrombolysis in myocardial infarction (TIMI) score is considered a tool for early risk stratification. Additionally, it helps predict the likelihood of adverse cardiac events. Primarily, it helps in making decisions about patient management. The need for this stratification is two-fold. Patients who initially present with signs and symptoms of unstable angina or non-ST elevated myocardial infarction require risk stratification. ![]() |
