Answer:

Mechanical advantage = 8

Step-by-step explanation:

It is given that,

A screw has 4 threads per centimeter.

The circumference of the screw, C = 2 cm = 0.02 m

The mechanical advantage of a screw is given by :


MA=(circumference)/(pitch).............(1)

Pitch of a screw is defined as the number of threads per inch on the screw i.e.

Pitch = 1 / number of threads per inch or cm

or pitch = 1/4


MA=(2)/(1/4)

MA = 8

Hence, the mechanical advantage of the screw is 8.
