The tower can be approximated as a vertical iron beam that is 300 m tall in winter when it is 35 degrees F. About how tall is the tower in summer when it is 75 degrees F? The linear expansion factor for iron is 12 x 10^-6/degrees C. Please give 3 digits of precision after the decimal.

The gap width is 1.610 cm when the temperature is 30.0°C. Determine the gap width when the temperature is 205°C. (Use 11 ✕ 10−6 (°C)−1 for the average coefficient of linear expansion for steel. Give your answer to at least three decimal places.)

How many degrees celcius does someone need to raise the temperature of a copper rod in order to increase its length by 5%? The linear expansion factor for copper is 17 x 10^-6/degrees celcius.

The first real length standard, adopted more than 200 years ago, was a platinum bar with two very fine marks separated by what was defined to be exactly one meter. If this standard bar was to be accurate to within +1.0 µm, how carefully would the trustees have needed to control the temperature? The coefficient of linear expansion is 9 × 10-6/C°.

The Eiffel tower in Paris is made primarily of iron, whose coefficient of linear expansion is about 10 x 10-6 / oC. On a cold day when the temperature is -10 oC the Eiffel tower is 300 m tall. Its height on a hot day when the temperature is 40 oC is

A gold wire 2.4 m long has its temperature lowered by 42oC. Assuming the linear coefficient of expansion has a constant value of 13 x 10-6 K-1 over that temperature range, calculate the change in length of the wire. Express your answer in mm.

Brass 0.030 m 5.0 µm Brass has linear thermal expansion coefficient a = 19 × 10-6rC . The picture shows a design defect in an electrical assembly: if the screw expands enough to touch the surface on the left, a dangerous short circuit will occur. The picture shows the assembly at 15°C. What is the maximum tempe ure the assembly can tolerate? 46.9°C 32.6°C 23.7°C 27.4°C 19.3°C
