Find the stresses on an inclined section through the element at an angle ? = 45°.The bar in Figure has a constant width of 35 mm and a thickness of 10 mm. Determine the maximum average normal stress in the bar when it is subjected to the loading shown.A propeller shaft is required to transmit 45 kW power at 500 rpm. It is a hollow shaft having inside diameter 0.6 times the outer diameter. It is made of plain carbon steel and the permissible shear stress is 84 N/mm^2. Determine the inner and outer diameters of the shaft.

Round up final answer to whole numberTen bolts of 10 mm diameter are used to connect two shafts as shown. If the mean diameter of the circle is d = 200 mm, and the failure shear stress of the bolt’s material is 70 MPa, determine the maximum permissible torque (N.m). Take F.S. = 1.05. (Input the answer with two decimal places; like 263.46, 3682.42, ....).Since each of the shafts AB, BC and CD shown in the figure consists of a solid circular bar, determine the magnitude of the stress in the shaft (MPa) at which the maximum shear stress occurs.
