Answer:

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.
