Question

What factor must be increased to give a machine a mechanical advantage greater than 1?

Answer 1

Load must be increase to give a machine MA greater than 1.

Explanation:

We know that,`M.A =` load/ effort #

`=>M.A prop L` [when effort is kept constant]
`=> M.A prop 1/ E` [when load is kept constant]
So, being M.A directly proportional to load, it is must to increase the load in-order to give a machine M.A more than 1 or decrease the load to give a machine M.A smaller than 1.
