The bar is built in atB and carries the vertical force P at end A. Given: P = 3 kN, R = 900 mm andα = 25°.1. Calculate the bending moment (kN-m) acting at section C.2. Calculate the torsional moment (kN-m) acting at section C.3. If the allowable torsional stress is limited to 65 MPa, calculate therequired minimum diameter of the bar (mm).ANSWERS: 1.14 kN-m; 0.25 kN-m; 60 mm

The flanges are to be bolted together. However,initially there is a 6⁰ mismatch in the location of the boltholes as shown in the figure. Determine the maximumshear stress(ksi) in each shaft after the flanges have beenbolted together. The shear modulus of elasticity for steelis 12 x 106 psi. Neglect deformations of the bolts and theflanges.

If TC = 250 lb-ft, determine the maximumshear stress developed in each material (in ksi). The moduliof rigidity for steel, aluminum, and bronze are 12 x 106 psi, 4x 106 psi, and 6 x 106 psi, respectively

The inner row has 6 nos. of 16mm diameterbolts spaced evenly in a circle of 250mm in diameter. The outer row of has 10 nos. of 25 mm diameter bolts spaced evenly in a circle of 500mm in diameter. If the allowable shear stress on one bolt is 60 MPa, determine the torque capacity of the coupling. The Poisson’s ratio of the inner row of bolts is 0.2 while that of the outer row is 0.25 and the bolts are steel, E =200 GPa.
