- The shown circular bar is fixed to the left wall. It has a diameter of 0.5 in and length of 60 in at 50 °F when it is unloaded. There is a gap of 0.08 inches between the bar end and the right opposite wall. The bar was simultaneously loaded axially with a load P and heated such that the temperature was raised from 50 °F to 130 °F along all the bars. The bar material has a modulus of elasticity = 15 x 10° psi and coefficient of thermal expansion = 10.6x106 1/°F. Determine the maximum magnitude of the load P such that the right opposite wall remains stress free.arrow_forwardI need the answer quicklyarrow_forwardcan you help me with detailed solution pls 2.

- I need the answer as soon as possiblearrow_forwardMechanics of deformable bodies. Two decimal places.arrow_forwardA cylindrical bronze sleeve (2) is held in compression against a rigid machine wall by a high-strength steel bolt (1), as shown in the figure. The steel [E = 200 GPa; a = 11.7 x 106/°C] bolt has a diameter of 29 mm. The bronze [E = 100 GPa; a = 22.0 x 106/°C] sleeve has an outside diameter of 74 mm, a wall thickness of 8 mm, and a length of L = 390 mm. The end of the sleeve is capped by a rigid washer with a thickness of t = 5 mm. At an initial temperature of T₁ = 14°C, the nut is hand-tightened on the bolt until the bolt, washers, and sleeve are just snug, meaning that all slack has been removed from the assembly, but no stress has yet been induced. If the assembly is heated to T2 = 59°C, calculate the normal stress (positive if tensile and negative if compressive) in the bronze sleeve. Answer in MPa rounded-off to 2 decimal places.arrow_forward
