Aluminum Steel A weight is suspended from two wires. One wire is steel and the other aluminium. The elastic modulus for steel is 192GPA and Aluminium 68GP.. Both wires have the same cross-sectional area 4.2mm² and initial length 2.75m. If the suspended weight is 580N, determine the magnitude of the stress in the steel wire. Enter your answer in MPa to one decimal place. Your Answer: Answer

Q6

The homogeneous bar ABC is supported by a pin at C and a cable that runs from A to B around the frictionless pulley at D. Find the stress (in psi) in the cable if its diameter is d = 0.57 in and the weight of the bar is 5305 lb. Round off the final answer to three decimal places.
