Answer:
Effort = 70 N
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 = [tex]\frac{Load}{Effort}[/tex]
In the given question, MA = 5 and the load = 350 N. So that;
5 = [tex]\frac{350}{E}[/tex]
E = [tex]\frac{350}{5}[/tex]
= 70
The effort applied to the machine is 70 N.
