The five 20mm-diameter rivets fasten the plate as shown in the figure to the fixed member. a). Determine the value of the load P so that the average stress of any rivet does not exceed 80MPa.b). What additional clockwise torque can be applied before the shearing stress exceeds 90MPa

If the maximum bending stress at section a–a is not allowed to exceed an allowable stress of 220 MPa, determine the maximum allowable force P that can be applied to the end E.

Load P is applied to joint D and the temperature increases by 50 °F. There are two steel (E = 29*10^6 psi; a = 6.5*10^-6/°F) AD and DC and a bronze (E = 16*10^6 psi; a = 9*10^-6/°F) BD with a length of 50 inches. Each bar is a 0.75 inch diameter. Find the deformation of every rod, the displacement at D, and the stress in each rod.
