Question

the mechanical advantage of a machine is 3. how much effort should be exerted on it so that it lifts a load of 60 N?

Answer 1

Answer:

The mechanical advantage of a machine is 2. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N. hope it helps!
