A screw has 4 threads per centimeter and a circumference of 2 centimeters. What is the mechanical advantage of the screw? 2 4 6 8

M.A = 8

Explanation:

Given the following data;

Circumference = 2cm

Number of threads = 4

To find the mechanical advantage (M.A);

But,

Pitch = 0.25

Substituting the values into the equation, we have;

M.A = 8

Therefore, the mechanical advantage of the screw is 8.

its a for sure man enjoy your correct answer

the only way i would see could be an autoclicker type software. but that is very time consuming.
