A flat bar is 3/8 inches thick and has a centrally located drilled hole of diameter D. The bar is subjected to a 4,000 lb tensile load. Compute the maximum tensile stress adjacent to the hole. a) If the bar is 2 inches wide and D=0.25 inches b) If the bar is 2.5 inches wide and D=0.5 inches c) If the bar is 3 inches wide and D=1.00 inches Answers: a) = 15,969.5 psi (using k=2.62) b) = 13,066.7 psi (using k=2.45) c) = 12,000 psi (using k=2.25) I have no idea how to come up with these answers. Could you help me go through the process of solving for these answers step by step?

Please help. Written on paper not typed on computer or keyboard please. Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

(BB) Q1: The shaft, as shown in Fig. is driven by pulley B from an electric motor. Another belt drive from pulley A is running a compressor. The belt tensions for pulley A are 1500 N and 600 N. The ratio of belt tensions for pulley B is 2.5. The diameter of pulley A is 150 mm and the diameter of pulley B is 480 mm. The allowable shear stress for the shaft material is 85 MPa. Taking torsion and bending factors as 1.25 and 1.5 respectively, find the shaft diameter. C # -100- A B -150-100 D TB2 All dimensions in mm. B A TAZ TAI TB1

PS.1 Find a real physical example of a mechanical structure or machine that has tensile stress present. (a) Make a clear labeled drawing of the situation. (b) Estimate the dimensions of the structure or machine and the magnitudes and directions of the forces that act on it. Show these on the drawing. Briefly explain why you estimate the dimensions and forces to have the nurnerical values that you assigned. (c) Calculate the magnitude of the stress.
