A copper (Young's modulus 1.1 x 1011 N/m2) cylinder and a brass (Young's modulus 9.0 x 1010 N/m2) cylinder are stacked end to end, as in the drawing. Each cylinder has a radius of 0.38 cm. A compressive force of F = 8600 N is applied to the right end of the brass cylinder. Find the amount by which the length of the stack decreases.
A vertical wire 2.1m long and of 0.0042 cm2 cross sectional area has a Young’s modulus of 2.00 x 1011 Pa. A 4.0 kg object is fastened to its end and stretches the wire elastically. If the object is now pulled down a little and released, the object undergoes vertical single harmonic motion. Find the period of its vibration.

A A steel wire is used to lift heavy object. The cable has a diameter of (5.25 + A) mm and an initial length of (24.5 + B) m. If the cable stretches 2.50 mm, what is the mass of the heavy object? Use 20.0 x 1010 Pa for Young’s modulus for steel. Give your answer in kg and with 3 significant figures. A= 0 b= 1
A=2 B=3 A steel wire is used to lift heavy object. The cable has a diameter of (5.25 + A) mm and an initial length of (24.5 + B) m. If the cable stretches 2.50 mm, what is the mass of the heavy object? Use 20.0 x 1010 Pa for Young’s modulus for steel. Give your answer in kg and with 3 significant figures.
20.) A 10.0 kg mass is attached to the end of a 2.00 m long brass rod, which has a diameter of 1.00 mm and negligible mass. The mass at the end is pulled, stretching the rod slightly, and then released. If the elastic modulus of brass is 9.10 × 1010 N/m2, then the frequency of the resulting oscillations is. ___Hz 19.) A U-shaped manometer, filled with a liquid of unknown density, is connected on one side to a vessel...
An 9.15-kg stone at the end of a steel (Young's modulus 2.0 x 10^11 N/m2) wire is being whirled in a circle at a constant tangential speed of 13.9 m/s. The stone is moving on the surface of a frictionless horizontal table. The wire is 4.40 m long and has a radius of 3.25 x 10^-3 m. Find the strain in the wire.
8. Young's modulus Y of aluminum is 7 x 101°N/m2 , If you apply 10' N force to end of a wire radius 1 cm, length 1 m) hanging from ceiling, how much will the length increase (a) 7cm (b) 0.00007m (c)2.29m (d) none of them solution : (d) (F/A) = Y(AL/L), thus AL = (FL)/(YA) = (104 x 1)/(7 x 1010 X7X (0.01)2) = 10-2/(77) = 0.045 x 10-?m
A particular human hair has a Young's modulus of 3.80 x 10 N/m² and a diameter of 150 um. If a 234 g object is suspended by the single strand of hair that is originally 15.0 cm long, by how much AL hair will the hair stretch? AL hair = m If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much ALA would the aluminum stretch? ALAI = ALA =...
