want to know how much heat the tube lost due to the material it is made of. Even if it is a small difference in temperature. It is a heat transfer problem material: Aluminum temperature touching cylinder: 65 Celcius temeprature inside cylinder 64.5 celsius  room temperature 24 celcius Tube measurements  outer radius r1 r1 = 4 in inner radius r2 r2 = 3 in

1.A composite component is comprised of a tube and a concentric rod running inside it, both with a length of 1.5 meters. The tube is made of copper and has inner and outer diameters of 60 mm and 100 mm, respectively, a coefficient of thermal expansion and elastic modulus of 17 ×10−6? and 117 GPa, respectively. The rod is made of aluminium with a diameter, coefficient of thermal expansion and elastic modulus of 50 mm, 23 ×10−6? and 80 GPa, respectively. If the composite is exposed to a temperature rise of 120°C, determine:1.1 The sense and magnitude of the stresses induced in the composite if it is not restrained. 1.2 The sense and magnitude of the stresses induced in the composite if it is partially restrainedwith an allowed free expansion of 0.3 mm.

An aluminum alloy [E-10,000 ksi; Oy- 40 ksi] pipe (1) is connected to a bronze [E-16,000 ksi; Oy - 45 ksi] pipe at flange B. The pipes are attached to rigid supports at A and C. Pipe (1) has an outside diameter of 2.425 in., a wall thickness of 0.21 in., and a length of L₁ - 8 ft. Pipe (2) has an outside diameter of 5.00 in., a wall thickness of 0.20 in., and a length of L₂ - 14 ft. If a minimum factor of safety of 2.1 is required for each pipe, determine: (a) the maximum load P that may be applied at flange B. (b) the deflection of flange B at the load determined in part (a). Deflection to the right is positive. (1) (2) C L2 Answer: (a) P- 80.4 (b) UB-i | L₁ P B kips ! in.

A square steel alloy plate 400 mm on a side has a 90-mm-diameter circular hole at its center. The plate is heated from 20°C to 45°C. The final diameter of the hole is ____ mm standard coefficient of thermal expansion: steel - 11.25x10^-6 / degrees celcius Aluminum - 23x10^-6 / degrees celcius
