The bar has a 40 mm by 20 mm rectangular cross section. The allowable normal and shear stresses on inclined surface a-a must be limited to 55 MPa and 30 MPa respectively. Determine the magnitude of the maximum axial force P that can be applied to the bar, and determine the actual normal and shear stresses acting on inclined plane a-a (MPa)

A solid steel bar of circular cross section has diameter d = 40 mm, length L = 1.3 m and shear modulus of elasticity G = 80 GPa. The bar is subjected to torques T acting at the ends. If the torques have magnitude T = 340 Nm, what is the maximum shear stress in the bar? What is the angle of twist between the ends? If the allowable shear stress is 42 MPa and the allowable angle of twist...

Q2. The figure shows a horizontal steel bar of thickness, 3 mm, loaded in steady tension and welded to a vertical support. Find the load F that will cause an allowable shear stress, Tallow = 140 MPa, in the throats of the welds. For the weldments, the electrodes are specified as E6010. For the electrode metal indicated, what is the allowable load on the weldment?

W 1. Ski Lift: A ski lift is supported by two bent arms, as shown in the figure. Each arm is offset by b=180 mm from the line of action of the total weight force W=12 KN. The allowable stresses gallow=100 MPa in tension (and Tallow=50 MPa in shear). Determine the minimum diameter d of the arms, just considering tensile stress. Show the location of the max. stress on the cross section shown. Hint: stresses caused by direct and bending...
