The radii of a wheel are 25cm and 5cm respectively. It is found that an effort of 40N is required to raise slowly a load of 160N. Find mechanical advantage

Explanation:

Mechanical advantage is defined as the ratio of the load to the effort applied to raise the load. If minimal effort is used to overcome a much larger load, that is when we have what is called mechanical advantage i.e a machine has been used to our advantage.

Mathematically, MA =  Load/Effort

Given parameters

Load = 160N

Effort = 40N

Required

Mechanical Advantage

Using the formula above

MA = 160N/40N

MA = 4

advantage

f=ma newton

f=100x2.5=250n

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
