The force is $F=61.0N$

enter image source here

The load is $L=24gN$

The radius of the axle is $r=14m$

The radius of the wheel is $R=54m$

The effort is $=FN$

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

Taking moments about the center of the axle

$F*54=24g*14$

$F=(24g*14)/54=61.0N$

The force is $F=61.0N$
