A straight rod consists of of 0.82 cm long piece of aluminum attached to a 2.84 cm long piece of steel. By how much will the length of this rod change if its temperature is increased from 11 degree celsiu to 28 degree celsius. The average coefficient of linear expansion of aluminum and steel is 2.5x10^-5 (celsius)^-1 and 1.2 x10^-5 (celsius)^-1 respectively.

An aluminum rod with a diameter of 2.5 cm and a length of 40 cm is held between two heat reservoirs. The colder reservoir is at 15°C. The thermal conductivity of aluminum (kT) is 238 W/mC° and 32 Watts of heat energy are flowing along the length of the rod due to conduction. What is the temperature of the other reservoir?

An aluminum measuring rod, which is correct at 5.0 C measures a certain distance as 88.42 cm at 35.0 C.Determine the error in measuring the distance due to the expansion of the rod. If this aluminum rod measures a length of steel as 88.42cm at 35.0 C, what is the correct length of the steel at 35 degrees C? The coefficient of linear expansion of aluminum is 22 x10^-6 C^-1.

Inside the house where the temperature is 20∘C20∘C, we measure the length of an aluminum rod with a micrometer MADE OF STEEL. (A micrometer is a device which measures distances very accurately.) We find the rod to be 10.0000 cm long. If we repeat this measurement outside where the temperature is-13.7 ∘∘C, what result would we obtain? Caution: the size of the micrometer is also affected by the temperature, so we no longer obtain the true length of the rod...

Problem #1 (35 pts.) A solid 5 cm by 5 cm square aluminum rod, with a 70 GPa modulus of elasticity, is stretched by an unknown axial load. The initial rod length is 1 m, and its final length (after applying the axial load) is 1.0005 m. Assume that a strain gauge (with a gauge factor of 2.2) is firmly affixed to the rod, its active axis aligned with the length of the rod. You may assume the strain gauge...
