Question

А 6061-T6 aluminum tube is used as a sleeve for a steel post Tool L2 as shown. When not loaded, and at a temperature of 60 F, both the tube and post have a length of 24 in. The system is subjected to a load P and the temperature is increased to 115 F Assume that both the tube and post are rigidly connected to the rigid cap. Determine the load P required to restrict the system's length change to an increase of 0.01 in. Material | 6061-T6, Aluminum Tool L2, Steel Alloy -1) Modulus of elasticity, E (ksi) | Coefficient of thermal expansion, α (oF 0.0x 103 13.1 x 10- 29.0 x 103 6.50 x 10-6 Cross section rigid cap Tool L2, Steel Alloy 6061-T6, Aluminum 24- 1.25 1.5- Express your answer in pounds to three significant figures. Enter positive value if the force direction is the same as shown in the free-body diagram, and negative value if its direction is opposite.
