Thermal Expansion

Part A The Concorde was a supersonic aircraft used for trans-Atlantic travel in the 1980s and 1990s, having a length of 61.6 m when sitting on the ground on a typical day when the temperature is 14.0°C. The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 29.0 cm. (The passenger cabin is on rollers, so the airplane expands around the passenger cabin.) Take the coefficient of linear expansion for aluminum to be a = 2.40x10-5 /°C. What is the temperature T of the Concorde's skin in flight? View Available Hint(s) IVO AXO ? T = °C

The ends Q and R of two thin wires, PQ and RS, are soldered (joined) together. Initially, each of the wire has a length of I m 10°C. Now, the end P is maintained at 10°C, while the end S is heated and maintained at 400°C. The system is thermally insulated from its surroundings. If the thermal conductivity of wire PQ is twice that of the wire RS and the coefficient of linear thermal expansion of PQ is 1.2 x 10--K -1, the change in length of the wire PQ is (a) 0.78 mm (b) 0.90 mm (c) 1.56 mm (d) 2.34 mm

Question 7 1 pt Question 8 1 pt Question 9 1 pt When an object gains or loses thermal energy, its temperature changes. This simulation shows how the magnitude of the temperature change depends on the mass of the object, its composition, and on the quantity of energy transferred to the object. The module simulates heating a substance. The substance always starts at 20.0 °C. Six different materials are available and the duration of heating and mass of the block can be adjusted. To run an experiment, select a Material, choose the Block Mass, and set the Heating Duration. Then press Heat. When the burner stops, the temperature change experienced by the block and the quantity of thermal energy added are displayed. To run another experiment, press Reset, change the settings, and press Heat again. < Next> (Introduction) Question 10 1 pt Question 11 1 pt Submit Answer Try Another Version 10 item attempts remaining

AY x, hence K- Comprehension-1 When a tensile or compressive load P is applied to rod or cable, its length changes. The change in length x which, for an elastic material is proportional to the force (Hook's law). Pax or P = kx The above equation is similar to the equation of spring. For a rod of length L. area A and young modulus Y, the extension x can be expressed as PL or P AY AY Thus rods or cables attached to lift can be treated as springs. The energy stored in rod is called strain energy & equal to Px. The loads placed or dropped on the floor of lift cause stresses in the cables and can be evaluated by spring analogy. If the cable of lift is previously stressed and load is placed or dropped, then maximum extension in cable can be calculated by energy conservation. If rod of length 4 m, area 4cm2 and young modulus 2 x 100 N/m2 is attached with mass 200 kg, then angular frequency of SHM (rad/sec.) of mass is equal to . (A) 1000 (B) 10 (C) 100 (D) 10 1.
