Knowing that the bending moment in the reinforced concrete beam is +95 kip·ft and that the modulus of elasticity is 3.625 × 106 psi for the concrete and 29 × 106 psi for the steel, determine the stress in the steel and the maximum stress in the concrete.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

Around steel bar, made from material with a yield stress of 750mpa, is loaded so that it has stresses co locations of maximum normal stress and maximum shear stress. use maximum shear stress and maximum distortion energy theories to calculate the safety factors for initial yielding failures.
