Determine the shear force and bending moment at the fixed end of a cantilever beam AB of span length 4 m, which is subjected to a uniformly distributed load of 4 kN/m throughout the entire span of the beam.

A load of 1960 N is suspended at the end of a steel wire. If the allowable tensile stress in the wire is 100 N/mm2, the minimum required diameter of the wire is approximately:

During a tensile test of a mild steel bar of 30 mm diameter under a load of 100 kN, the stress induced in the bar is approximately:
