Transcription: In this example, we're trying to determine the mechanical advantage of a screw. In this particular case, the screw has a head with a diameter of 0.30 inches. The pitch of the screw is 0.05 inches. Now, remember what pitch means. Pitch is the distance between the threads. So the distance between the threads is 0.05 inches. The equation for the mechanical advantage of a screw says that mechanical advantage is the circumference of the screw's head divided by the pitch. So the first thing we have to do is determine the circumference. Now the circumference is not given but we can calculate it becau ...
