if a hammer has a resistance arm of 3 inches and the effort arm is 15 inches. what is the mechanical advantage?

ma = 10
ma = 2
ma = 15
ma = 5

Option D

MA=5

Explanation:

Mechanical advantage is the  the ratio of the output force to the  input force hence

Substituting 15 inches for the effort arm length and 3 inches for the load arm length then we obtain the mechanical advantage as
