How long does it take to write 1 or 2 paragraphs for you?

A simply supported beam having a span l =3.6m is to carry a uniformly distributed load of
intensity w = 1600kg/m. The cross-section is to be rectangular with depth h and width b = h/2. If
the allowable bending stress in tension or compression is σ w = 84 kg/cm 2 . What is the required
depth h for the cross-section?
