2. The coefficient of linear expansion of steel is 12 X 10° K'. What is the change in length of a 25-m steel bridge span when it undergoes a temperature of 40 K? 2. The
The coefficient of linear expansion of steel is 12 × 10-6 K-1. What is the change in length of a 25-m steel bridge span when it undergoes a temperature change of 40 K from winter to summer?
A container is filled to the brim with 1.5 L of mercury at 20°C. The coefficient of volume expansion of mercury is 1.8☓10-4 (°C)-1. As the temperature of the container and mercury is increased to 55°C, a total of 7.7 mL of mercury spill over the brim of the container. Determine the linear expansion coefficient of the material that makes up the container.
The coefficient of linear expansion of a mystery metal alloy is 1.20 x 10-5 K 1. At 20.0° C a rod made of this alloy has a length of 11.9200 m. The rod is cooled to -29.0° C. Calculate the change in length (AL) of the rod. Remember that a negative change in length means that the length decreases, and a positive change in length means that the length increases. (There must be three significant figures in your answer.) x...
QUESTION 7** On a 1 m square plate is a hole of area A 0.3 m2 at T: 200 K The plate is made of a material whose linear thermal expansion coefficient is α increase AA of the area of the window at T-300 K compared with that at T- 200 K? 13 x 10 6 K l what is the ΔΑ: 5.3x10-4m2 ΔΑ = 7.8 × 10-4 m2 ΔΑ = 9.3 × 10-4 m2 ΔΑ =11.2×10-4 m2 4A =...
The coefficient of linear expansion for some common materials are listed in the table. Material polycarbonate aluminum brass Suppose Mary would like to design an emergency overheating alarm using one of these materials. In her design, at room temperature (23.0°C), a 8.26 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 0.0258 cm, the button will be activated,...
