The force is #F=36.2N#

enter image source here

The load is #L=24gN#

The radius of the axle is #r=4m#

The radius of the wheel is #R=26m#

The effort is #=FN#

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

Taking moments about the center of the axle

#F*26=24g*4#

#F=(24g*4)/26=36.2N#

The force is #F=36.2N#
