2. The drawing shows two thin rods, one made from aluminum Midpoint [a = 23 x 10-6 (C°)-'] and the other from steel [a = 12 × 10-“ (C°)-']. Each rod has the same length and the same initial temperature and is attached at one end to an immovable wall, as shown. The temperatures of the rods are increased, both by the same amount, until the gap be- tween the rods is closed. Where do the rods meet when the gap is closed? (a) The rods meet exactly at the midpoint. (b) The rods meet to the right of the midpoint. (c) The rods meet to the left of the midpoint. Aluminum Steel
The 40mm diameter steel rod AB shown in Figure 2 is resting on frictionless rollers between two steel plates. End A is just touching the left hand steel plate. 2. Steel plate Steel plate A В 1500mm 1mm Figure 2 There is a gap of 1mm between the end B and the right hand side steel plate. The temperature of the rod increases by an amount AT and this increase in temperature causes the two ends of the rod to press against the steel plates. This action causes the right hand steel plate to move to the right by 0.5mm while the left hand plate does not move. The Young's modulus value for steel is 210,000N/mm?. Taking any assumptions that you deem necessary calculate the increase in temperature AT required to cause the rod to buckle.
What will be the rise in temperature in 30 minutes of a block of copper of 500-gram mass if it is joined to a cylindrical copper rod 20 cm long and 3.0 mm in diameter when a temperature difference of 80 degree Celsius is maintained between ends of the rod? The thermal conductivity of copper is 1.02 cal/cm2-sec-°C/cm (neglect heat losses). Please include FBD

An ideal mono-atomic gas is confined in a cylinder with the help of a piston that can slide inside the cylinder without friction. The cylinder I placed on a horizontal platform in a vacuum chamber. The walls of the cylinder and the piston are made of heat insulating materials. Initially the temperature of the gas is 'T, and the piston stays in equilibrium. The temperature of the gas is quickly increased n times and then the gas is allowed to expand. If the piston rises and again acquires an equilibrium state, find the temperature of the gas in this new equilibrium state.

Question 5: Z=62 a. An iron sphere of mass (Z + 300)g is kept in a container having boiling water (100 °C). If the temperature of the sphere is 25.5°C, how much heat energy is absorbed by the iron sphere? Consider the specific heat of iron as 452J/kg. b. The wall of an industrial furnace is constructed from (Z + 3) cm thick fireclay brick having a thermal conductivity of 1.7 W/mK. Measurements made during steady-state operation reveal temperatures of 530°C and 375°C at the inner and outer surfaces, respectively. Find the rate of heat loss through a wall which is (Z + 5) cm by (Z + 3) m on a side.
Calculate the heat transferred from the cube-shaped iron mass (a = 30 cm) to the environment at 20 ° C with all surfaces at a temperature of 100 ° C. (Assume that the heat is only from the surfaces, the inner parts of the surfaces are insulated.)

A circular nylon [E = 8 GPa; ν = 0.35; α = 22 ×10-6/°C] disk with a circular hole in its center is shown. At an initial temperature of Ti = 15°C, the outer diameter of the disk is D = 200 mm, the diameter of the central hole is d = 55 mm, and the thickness of the disk is t = 22 mm. At a final temperature of Tf = 51°C, determine:(a) the change in diameter Δd of the central hole (assume an increase Δd as positive, otherwise as negative).(b) the change in thickness Δt of the disk (assume an increase Δt as positive, otherwise as negative).(c) the normal strain in the circumferential direction around the outside of the disk
