Sample Questions

1multiple correct

Which of the following are characteristics of an ideal machine?

Show answer

No friction between parts, Weightless parts, 100% efficiency, Output work equals input work

An ideal machine has no friction, weightless parts, 100% efficiency, and output work equals input work. M.A. can be any value depending on the machine type.

2multiple correct

Which of the following are examples of Class II levers?

Show answer

A nutcracker, A wheelbarrow

In a Class II lever, the load lies between the fulcrum and the effort, and its mechanical advantage is greater than 1. A nutcracker and a wheelbarrow are standard examples of Class II levers. Scissors and a crowbar are Class I levers because the fulcrum lies between load and effort.

3multiple choice

The mechanical advantage of a single fixed pulley is:

Show answer

1

A single fixed pulley has M.A. = 1 because the load and effort are equal. Its main advantage is changing the direction of effort.

4multiple choice

A single movable pulley has a mechanical advantage of:

Show answer

2

A single movable pulley has M.A. = 2 because the load is supported by two segments of the rope, so effort = Load/2.
