This video is answering the question of how does a pulley work.

This Short Answer question also works as a part of the AP Physics C: Mechanics curriculum.

A day does not go by without using simple machines. This program explores the six major types of simple machines with practical, colorful examples of each. Vivid video footage illustrates how each of the following simple machines works...

To solve problems like these, make isolated cut selection to find each of the variables one at a time. Then use that fact that under reasonable assumptions (massless rope and frictionless pulleys) then the tension in the cable must be...

In this video, we'll explore the basics of induction motors. We'll cover topics like the theory behind induction motors, the different types of induction motors, and how induction motors work.

If a pulley is in static equilibrium and the following is true:

1) Rope is mas
sless
2) Pin is fr

ictionless

Then the tension in the cable will be constant everywh

ere along the cable.

There is only 1 force...
