Question 4 Temperature Determine the stresses in the compound bar shown if the temperature of the bar is raised by 50°C. The left-hand part of the bar is made of solid steel circular section of diameter 20 mm and the right- hand part of solid copper of diameter 30 mm. (Hint: Calculate change in length of steel and copper due to temperature when unrestrained. For an unknown load 'P' in both steel and copper write an equation giving change in length for each and equating this to the total change in length due to temperature. After you have found P' solve for stresses.) Enel = 200 GPa, Ecoppe= 120 GPa, atel 10 x 10/"C and acopur 17 x 10 /"C. Steel Copper 200 mm 200 mm

In this problem you will consider the effect that thermal expansion due to temperature will have on Archimedes' principle. Take the densities of water and copper at 0ºC to be 1.00 × 103 kg/m3 and 8.90 × 103 kg/m3, respectively. a. Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 0°C. b. Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 95°C. Assume the volume expansion coefficient of copper is βC = 5.10 × 10-5 1/°C.
