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

Answer:

Mechanical advantage of the wheel and axle is 32.5

Explanation:

Given that,

The radius of the axle,[tex]r_a=0.8\ cm[/tex]

The radius of wheel ,[tex]r_w=26\ cm[/tex]

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

[tex]MA=\dfrac{r_w}{r_a}[/tex]

[tex]MA=\dfrac{26}{0.8}[/tex]

MA = 32.5

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