A ruler is accurate when the temperature is 23.5 °C. When the temperature drops to -14.0 °C, the ruler shrinks and no longer measures distances accurately. However, the ruler can be made to read correctly if a force of magnitude 1.22 x 103 N is applied to each end so as to stretch it back to its original length. The ruler has a cross-sectional area of 1.46 x 10-5 m2, and it is made from a material whose coefficient of linear expansion is 2.5 x 10-5 (C°)-1. What is Young's modulus for the material from which the ruler is made?

The Golden Gate Bridge in San Francisco has a main span of length 1.28 km, one of the longest in the world. Imagine that a steel wire with this length and a cross-sectional area of 4.00 x 10-6 m2 is laid on the bridge deck with its ends attached to the towers of the bridge, on a summer day when the temperature of the wire is 35.0°C. (a) When winter arrives, the towers stay the same distance apart and the bridge deck keeps the same shape as its expansion joints open. When the temperature drops to -10.0°C, what is the tension in the wire? Take Young’s modulus for steel to be 20.0 x 1010 N/m2.

(c) Explain how your answers to (a) and (b) would change if the Golden Gate Bridge were twice as long.

A brass bar is joined at one end to a 70 cm copper bar and at the other end with boiling water at 1 atm. In order to achieve conductive heat transfer, the copper-free end is brought into contact with a mixture of water and ice also at 1 atm. Both bars have a cross sectional area of 0.00500 m2. The sides of the rods are insulated, so there is no heat loss to the surroundings. If after 5 minutes 50 g of ice melts, find the length of the brass bar.
One end of a 0.33-m copper [k = 390 J/(s·m·C°)] rod with a cross-sectional area of 1.0 × 10-4 m2 is driven into the center of a sphere of ice at 0°C (radius = 0.14 m). The rod is horizontal and its other end is fastened to a wall in a room. The rod and the room are kept at a constant temperature of 21°C. The emissivity of the ice is 0.93. What is the ratio of the heat per second gained by the sphere through conduction to the net heat per second gained by the ice due to radiation? Neglect any heat gained through the sides of the rod.
