Question

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

Answer 1

Answer:

Mechanical advantage of the wheel and axle is 32.5      

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 :

$MA=\dfrac{r_w}{r_a}$

$MA=\dfrac{26}{0.8}$      

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
