The assembly consists of two red brass C83400 copper alloy rods AB and CD of diameter 30 mm, a stain less 304 steel alloy rod EF of diameter 40 mm, and a rigid cap G. The part ist fix at both ends (A, C and F) Determine: a. The reaction force at point A, Cand F b. The deflection of point B, E, D The average normal stress develoned in rods AB CD and FF

A rigid bar ABCD is supported by two bars as shown in the figure. There is no strain in the vertical bars before load P is applied. After load P is applied, the normal strain in rod (1) is -1350 µm/m. Determine the normal strain in rod (2) if there is a 1-mm gap in the connection at pin C before the load is applied.

Two steel rods are welded together (see figure);the seam is oriented at angle θ = 50°. The stresses onthe rotated element are σ x1 = 10 ksi,  σy1 = -12 ksi,and τx1y1 = -5 ksi. Find the state of plane stress onthe element if it is rotated clockwise to align the x1axis with the longitudinal axis of the rods.
