Thin strips of brass and copper of equal length are used to construct a bimetallic strip. When the strip is heated, due to the difference in the coefficient of linear expansion of the two metals, the brass strip will have a greater increase in length than the copper strip, causing them to bend into an arc with the brass on the outside of the curve. When the temperature of s by 25.8 C, the angle subtended by the two ends...

Now the friends use data obtained in the simulation to identify materials A-E. They calculate and record the value of α for each material and use the table below to identify it. (Hint: The simulation rounds some of the data to two-digit accuracy, so calculate all coefficients of linear thermal expansion using AT 50.)

The table at the right includes a few coefficients of linear expansion for some materials. You need to design an emergency overheating alarm using one of these materials. In your design, at room temperature (23.0°C), a 8.01 cm long cylinder of the material will sit with one end against a wall and the other just barely touching a button. Once the heat causes the cylinder to lengthen by 0.0238 cm, the button will be activated, turning on the alarm. At...

A rod with a length of 1.6 m is made of brass, which has a coefficient of linear expansion of 1.90 ✕ 10−5 (°C)−1. It is initially at a temperature of 27°C. What is the change in length of the rod if the temperature drops to 0.0 C? ( give absolute value in units of mm) Find the absolute value of the fraction by which the rods length changes between two temperatures. ΔL L0

1. The George Washington Bridge crosses the Hudson River between New York and New Jersey. The span of the steel bridge is about 1.70 km. What might be the difference between the maximum span and minimum span over the course of a year, if the temperature can vary from a low of −15.0°F in winter to a high of 106°F in summer? Expansion coefficient of steel is α = 12.0 × 10^−6 K^−1. 2. A 2.30 m length of copper...
