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.

Steel Young's Modulus (Y) 20 X 1010 N/m2 Shear Modulus (S) 8.1 X 1010 N/m2 Bulk Modulus (B) 16 X 1010 N/m2 The table to the above represents various properties of steel. You have steel wire 4.4 meters in length that stretches 0.12 cm when subjected to a force of 300 N. 1)What is the diameter of the wire? d1 =__________ cm 3)What would the diameter of the wire be if you wanted the wire to stretch 0.06 cm less...
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
Assume that Young's Modulus for bone is 1.50 ✕ 1010 N/m2 and that the bone will fracture if more than 1.50 ✕ 108 N/m2 is exerted. (a) What is the maximum force that can be exerted on the femur bone in the leg if it has a minimum effective diameter of 2.70 cm? (b) If a force of this magnitude is applied compressively, by how much does the 28.0 cm long bone shorten?
Steel is very stiff, and Young's modulus for steel is unusually large, 2 × 1011 N/m2. A cube of steel 17 cm on a side supports a load of 58 kg that has the same horizontal cross section as the steel cube. (a) What is the magnitude of the "normal" force that the steel cube exerts on the load? F= N (b) What is the compression of the steel cube? That is, what is the small change in height of...
A shearing force of 1250 N is applied to a brass rod with a length of 25.0 m and radius r = 1.27 cm. The shear modulus of brass is 35.0 x 109 N/m2. As a result the rod is sheared through a distance in mm of:
Assume that Young's Modulus for bone is 1.50 *10^10 N/m2 and that the bone will fracture if more than 1.50 *10^8 N/m2 is exerted. (b) If a force of this magnitude is applied compressively, by how much does the 27.0 cm long bone shorten? in "mm"
A sound wave travels through a solid copper cylinder that has radius of 1.29x10-3m, and length L=10.0m, and mass m=0.468kg. Copper has a Young's modulus of 1.10x10-11N/m2. How long does it take the sound wave to travel from one end of the cylinder to the other?
Young’s modulus for a brass mixture is 8.96 x 10 11 Pa. A 225 N object is applied to the end of the 4 m length of brass wire. Find the increase in length. The diameter is 1.5mm.
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.
