5. If the lengths of two bars of different solids are inversely proportional to their respective coefficients of linear expansion at the same initial temperature, the difference in length between them will be constant at all temperatures. That means one way to construct a device with two points whose separation remains the same in spite of temperature changes is to bolt together one end of two bars having different coefficients of linear expansion as shown below. What should be the lengths of a steel (a = 11 x 10° / C°) and a brass (a = 19 x 10° / C°) bar at 0°C so that at all temperatures their difference in length is 0.30 m? 1

= A steel rod with a length of I 1.55 m and a cross section of A = 3.04 cm² is held fixed at the end points of the rod. What is the size of the force developing inside the steel rod when its temperature is raised by AT = 25.0 K? The coefficient of linear expansion for steel is a = 1.17x10-5 1/K, and the Young modulus of steel is E = 200.0 GPa. Submit Answer Tries 0/12
If a 0.69 km (at -12°C ) section of straight railroad track made of steel is assumed to behave as a single piece, what is the difference in the length of the track between a cold winter day (-12°C) and a hot summer day (+38°C)? The coefficient of linear expansion (α) of steel is 1.2 × 10-5 °C-1.[1 km = 1,000 m]
A Pyrex flask in a refrigerator at –7°C is filled to the top and holds exactly 1000 cm³ of ethyl alcohol. If the refrigerator fails, how much alcohol spills by the time the temperature reaches 28°C? The coefficient of volume expansion of ethyl alcohol is 0.00112 (°C)-!. Ignore the expansion of the flask. Answer in units of cm³.

During an all-night cram session, a student heats up a 0.807 liter (0.807 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 15.5 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 98.0 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?
Suppose you have two meter sticks, one made of steel and one made of invar (an alloy of iron and nickel), which are the same length (1.00 m) at 0°C. The coefficients of volume expansion for steel and invar are 3.6 × 10-5 /°C and 2.7 × 10-6 /°C respectively. apparently, you need to use the volume expansion formula below & have B=3a. have no idea how to turn the length into a volume for this problem. have no idea what value alpha is...
Thank u! A steel rule is calibrated for measuring lengths at 20.00°C. The rule is used to measure the length of a Vycor glass brick: when both are at 20.00°C, the brick is found to be 30.90 cm long. If the rule and the brick are both at 85.00°C, what would be the length of the brick as measured by the rule? Coefficient of linear expansion a for steel is 12.0 x10^-6 K-1 and for glass (Vycor) is 0.750 x 10^-6 K^-1.
During an all-night cram session, a student heats up a 0.304 liter (0.304 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 18.3 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 96.9 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?
