Question

The two cylindrical rod segments are fixed to the rigid walls such that there is a gap of 0.01in between
them when T1 = 60°F. Determine the larger temperature T2 required in order to just close the gap
without producing stresses in the rods? Each rod has a diameter of 1.25in. Take aal = 13 x 10-6 in/in °F,
Eal = 10* ksi, acu = 9.4 x 106 in/in °F, Ecu = 15 x 10° ksi.
0.01in →
Copper
Aluminum
12in
6in

1. Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 17 -L capacity when at 10 °C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95 °C operating temperature, given that the fluid's volume coefficient of expansion is ß= 400 ×10-6/°C? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95 °C. The volume coefficient of expansion of copper is 5.1 x 10-5/°C. Hint: Consider the expansions of both the fluid and the radiator. AV: L
