How to rotate a point 270 degrees counter clockwise
👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

Finding angular velocity of a rotating bar using sum of moments - Method 3
Step 1) Free body diagrams. Step 2) Invent necessary variables. Step 3) Use F=ma, T=I alpha - it's easier to take moments about O. Step 4) Solve for alpha. Step 5) Use chain rule to figure out w based off definitions of alpha and omega....
