Q: The solid cylinders AB and BC are bonded together at B and are attached to fixed supports at A and C. Knowing that the modulus of rigidity is 26 GPa for aluminum and 39 GPa for Aluminum 300 mm brass, determine: 38 mm T=1.2 kN.m a) Maximum shearing stress in cylinder AB Ans AB 27.85MPA Brass a) Maximum shearing stress in cylinder BC 450 mm Ans T 36.7MPA 50 mm C

13 Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Knowing that the average normal stress must not exceed 175 MPa in rod AB and 150 MPa in rod BC, determine the smallest allowable values of d and d 300 mm 40 kN 250 mm 30 kN Fig. P1.3 and P1.4

The cantilever beam AB will be installed so that the 60-mm side forms an angle β between 0 and 90° with the vertical. The 660-N vertical force P is applied at the center of the free end of the beam. Determine the value of β for which the normal stress at point a is a maximum and the corresponding value of that stress. (Round the final answer to two decimal places.)
