Explanation:

Question 15

The effort force is the force applied to the machine, while the force applied by the machine is the resistance or output force. So the statement is false.

A lever is defined as a bar that can pivot around a fixed point (fulcrum). A ramp is an inclined plane, a screw is a different simple machine, and fulcrum is the fixed point, not the bar.

Answer:

False
