Question

Mechanical advantage allows you to apply a force over a ___________ distance to ___________ the distance an object moves.

A) long, decrease
B) short, decrease
C) long, increase
D) short, increase

Answer 1

The answer is D.
With mechanical advantage, less work is put in for a better result.
It can apply force in a shorter distance, but increase distance itself.

Answer 2

Answer;

D) short, increase

Mechanical advantage allows you to apply a force over a short distance to increase the distance an object moves.

Explanation;

• Mechanical Advantage of a machine is a measure of the ratio of output force to input force in a system. It tells you how many times the machine multiplies force. A machine can increase force and distance but not at the same time.
• In the force-distance trade-off if the force increases then the distance would decrease. They can not both increase at the same time.
