a) 5 b) 200 c) 500 d) 2000

Output force, F' = 300 N

Explanation:

It is given that,

Input force acting on the wheel, F = 100 N

From the figure,

Radius of the wheel, r = 3 cm

Radius of the axle, r' = 1 cm

The mechanical advantage of the wheel and axle is given by :

MA = 3

Another definition of mechanical advantage is given by :

MA = output force/ input force

F' = 300 N

So, the output force of the wheel and axle is 300 N. Hence, this is the required solution.
