Question

If the system has a mechanical advantage of 5 and the load of 350N.What effort is needed to lift the weight? Provide your answer in newtons​

Answer 1

Effort = 70 N

Step-by-step explanation:

A machine is a device that can be used to overcome a load by the application of a minimal effort. For a practical machine, mechanical advantage (MA) is the ratio of the load (L) overcome to the effort (E) applied.

i.e MA =
`(Load)/(Effort)`

In the given question, MA = 5 and the load = 350 N. So that;

5 =
`(350)/(E)`

E =
`(350)/(5)`

= 70

The effort applied to the machine is 70 N.
