How would a pulley be better than a ramp?

The pulley allows the re-direction of force by 180 degrees. A ramp cannot do that. Say you need to lift an engine out of a car's engine bay. You would use a pulley because as you pull straight down the engine goes straight up. That presumes that you weigh more than the engine.


What are some simple machine questions that can help students understand the concept of simple machines better?

Here are some simple machine questions that can help students understand the concept better: How does a lever make it easier to lift heavy objects? What are the different types of pulleys and how do they help in lifting loads? How does an inclined plane reduce the amount of force needed to move objects uphill? What is the purpose of a wheel and axle in making tasks easier? How does a screw help in holding objects together or lifting loads? Why is a wedge considered a simple machine and how is it used in everyday life? How do gears work together to transfer motion and force efficiently? What are some examples of compound machines that combine multiple simple machines to perform tasks?

Where do you place the fulcrum to get the most lifting power from a simple lever?

A lever's mechanical advantage is the ratio of the effort arm to the load arm. The shorter the load arm, the greater the lifting power, so the closer the fulcrum is to the object being lifted, the better.


What is the benefit of a screw?

A screw provides a mechanical advantage by converting rotational motion into linear motion, making it useful for holding objects together or lifting heavy loads with less effort. Screws also offer better grip and stability compared to other fasteners like nails.

Do objects flost better in freshwater or in salt water?

Objects float better in salt water. It is more dense, therefore, it is more difficult to move through.
