SUMMARY
The problem involves calculating the weight of a wheel with a radius of 0.5m that is being moved over a kerb of height 0.2m. A horizontal force of 240N is applied at the axle of the wheel. By applying the moment equation, Moment = Perpendicular force x distance, it can be established that the weight of the wheel is 180N, as this is the force required to maintain equilibrium while moving the wheel over the kerb.
