Mechanisms: Inclined Planes, Wedges, and Screws

The video tutorial covers three types of simple machines: inclined planes, wedges, and screws. It explains how inclined planes provide mechanical advantage by allowing easier lifting of loads. Wedges are described as moving inclined planes used for splitting, with similar mechanical calculations. Screws are detailed with their parts and how they provide mechanical advantage, including terminology like diameter and threads per inch.

What is an inclined plane and how does it help in lifting loads?

Explain the mechanical advantage of an inclined plane and how it is calculated.

Describe the function of a wedge and provide an example of its use.

How does the length of a wrench affect the mechanical advantage when using a screw?

What is the significance of the diameter and threads per inch in a screw?
