For a fixed-fixed nickel column with height 1.2 m, find the maximum radius to 3 significant digits required to sustain a critical load of 0.1 GN.

A compound bar is subjected to a compressive force of P=556 kN by means of a rigid endplate at the top. If the length of the bar is 876mm, determine the stress in the alurninum core. Answer in MPa. Round off your final answer to 2 decimal places. 25 mm Brass core E = 105 GPa a = 20.9 x 10-6/°C Aluminum shell E = 70 GPa Q = 23.6 x 10-6/°C 60 mm

Problem 1 An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown. Axial loads are applied at the positions indicated. Aluminum Steel A=800mm2 A=1000mm2 Bronze A=700mm? 4P 2P 500mm 600mm 700mm 1. What is the maximum value of P that will not exceed the axial stress bronze of 105 MPa? 2. What is the maximum value of P that will not exceed the axial stress in aluminum of 90 MPa? 3. If P=10KN, what is the axial force to be carried by the aluminum in KN? 4. If P is 5KN, what is the axial stress of steel?

At what temperature in terms of ΔT will the aluminum and steel segments shown have numerically equal stresses when the load P = 200 kN?
