Name ________________________________________ Seat Number ___________________ Please note that unless your work is legible, and presented in a logical order, you will receive no credit for the solution. Problem 1) Determine the maximum stresses induced in sections AB and BC of the bar ABC (all one bar welded together.) Bar AB is a solid 6 feet long aluminum bar with a diameter of 6 inches, E = 10x10^3 ksi, G = 4x10^3 ksi, and alpha = 13x10^-6 in/in per degree F. Bar BC is an solid 8 foot long steel bar with a diameter of 2 inches, E = 30x10^3 ksi, G = 11x10^3 ksi, and alpha = 6.6x10^-6 in/in per degree F. The torque applied to the structure is T = 15 kip feet. Also, determine the rotation of point B on the shaft, in degrees. Problem 2) Determine the maximum stresses induced in the same bar ABC as shown in problem 1 above, but with the load

Unformatted text preview: changed to a single load P = 100 kips as shown below. Also, determine how far point B on the shaft will move after the load is applied. Problem 3) Determine the shear and moment 2 m from the right end of the beam shown below: Problem 4) If the right end of the shaft of problem 1 were disconnected from the wall, what would the maximum stress in the shaft change to and where would this stress occur on the shaft? EXACTLY where on the shaft? Problem 5) If the right end of the shaft of problem 2 were disconnected from the wall, what would the maximum stress in the shaft change to and where would this stress occur on the shaft? EXACTLY where on the shaft?...
