For a cantilever with a uniformly distributed load W over its entire length L, the maximum bending moment is

A member is balanced at its end by two inclined members carrying equal forces. For equilibrium the angle between the inclined bars must be

For keeping the stress wholly compressive the load may be applied on a circular column anywhere within a concentric circle of diameter

A three hinged arch is loaded with an isolated load 1000 kg at a horizontal distance of 2.5 m from the crown, 1 m above the level of hinges at the supports 10 metres apart. The horizontal thrust is

In a solid arch, shear force acts
