2. Moment of a force When a machine element is loaded transversely, the loads cause
bending of the element * Skateboard acts as a simply supported beam

summary Real-life example quiz
Skateboard acts as a simply supported beam
The bending produces deflection of the member. This deflection produces mechanical strain, which in turn produces mechanical stress (Hook’s law). When the stress developed exceeds the elas-tic limit of the beam material, the beam fails.
