Question

The number of times a machine multiplies the effort force is?

A. resistance force
B. effort distance
C. mechanical advantage
D. efficiency

wanna help? (:

Answer 1

C. mechanical advantage

Answer 2

Okay whats your reason? (:

Answer 3

because mechanical advantage is the number of times a machine multiplies the effort force. It is calculated by MA equals resistance force divided by effort force.

Answer 4

C.
"In physics and engineering, mechanical advantage, gearing (MA) [1] is the factor by which a mechanism multiplies the force or torque applied to it."
