Question

What is the mechanical advantage of a machine which lifted a load of 30N is 5.What is the effort applied?

Answer 1

We know that:

Mechanical advantage is the ratio of load to effort.

MA = Load / Effort

So:

==> 5 = 30 N / E

==> 5 E = 30 N

==> E = 30 N / 5

==> E = 6 N

The effort is 6 N
