A machine has a mechanical advantage of 0.6. What force should be applied to the machine to make it apply 600 N to an object?

1000N is needed to be applied.

Explanation:

Machines make doing work easier. They allow us use small effort to carry out work on huge amount of load.

The mechanical advantage of a machine;

(M. A) = load/effort

M. A = 0.6

Load = 600N

effort = ?

0.6 = 600/effort

effort = 600/0.6

effort = 1000N
