1–85. The beam is made from southern pine and is supported by base plates resting on brick work. If the allowable bearing stresses for the materials are (spine)allow = 2.81 ksi and (sbrick)allow = 6.70 ksi, determine the required length of the base plates at A and B to the nearest 1/4 inch in order to support the load shown. The plates are 3 in. wide.
1–86. The two aluminum rods support the vertical force of P = 20 kN. Determine their required diameters if the allowable tensile stress for the aluminum is sallow = 150 MPa.
1–87. The two aluminum rods AB and AC have diameters of 10 mm and 8 mm, respectively. Determine the largest vertical force P that can be supported. The allow
