A horizontal tension member is to be constructed of two pieces of plastic glued along the incline pq at an angle of 30 deg with the horizontal. The allowable stresses on the glued joint in tension and shear are 5MPa and 3MPa respectively. Determine the largest load P. Assume that the strength of the glued joint controls the design. The cross-sectional area of the bar is 225 mm2.

A 62.6-kN vertical load P is applied at the corner of the square cross section of the steel compression member AB, which is free at its top A and fixed at its base B. Knowing that for the grade of steel used oy=345 MPa and E= 200 GPa, and using the allowable-stress method, determine the smallest allowable dimension d. B D 1.5 m The smallest allowable dimension dis mm.
