Question

What is the mechanical advantage of the wheel and axle shown below?

A. 32.5
B. 21.9
C. 20.8
D. 28.5

Answer 1

Mechanical advantage of the wheel and axle is 32.5

Step-by-step explanation:

Given that,

The radius of the axle,
`r_a=0.8\ cm`

The radius of wheel ,
`r_w=26\ cm`

We need to find the mechanical advantage of the wheel and axle. It can be calculated as :

`MA=(r_w)/(r_a)`

`MA=(26)/(0.8)`

MA = 32.5

So, the mechanical advantage of the wheel and axle shown below is 32.5 . Hence, this is the required solution.

Answer 2

The correct answer is A. 32.5

Mechanical advantage is the ratio of force that is input into a machine to the force output.

Mechanical advantage of a wheel and axle is calculated by dividing the radius of the wheel by that of the axle.

MA=R/r where R is the radius of the wheel and r is the radius of the axle.

Substituting for the values in the question gives:

MA=26cm/0.8cm

=32.5
