Answer:

The force is #F=52N#

Explanation:

enter image source here

The load is #L=5gN#

The radius of the axle is #r=24m#

The radius of the wheel is #R=8m#

The effort is #=FN#

The acceleration due to gravity is #g=9.8ms^-2#

Taking moments about the center of the axle

#F*8=5g*24#

#F=5g*24/8=52N#

The force is #F=52N#
