particular object undergoesstress of 50N/m2 and exhibits strain of6.2 x 10-8 what’s the Young's Modulus
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.
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 particular human hair has a Young's modulus of 3.18 × 109 N/m2 and a diameter of 152 μm. If a 268 g object is suspended by the single strand of hair that is originally 16.0 cm long, by how much A L hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much Δ LAI would the aluminum stretch? If the strand of hair is...
A particular human hair has a Young's modulus of 3.38×109 N/m2 and a diameter of 148 μm. If a 250 g object is suspended by the single strand of hair that is originally 20.0 cm long, by how much Δ? hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much Δ?(Al) would the aluminum stretch? If the strand of hair is modeled as a spring,...
An 14.3-kg stone at the end of a steel (Young's modulus 2.0 x 1011 N/m2) wire is being whirled in a circle at a constant tangential speed of 14.3 m/s. The stone is moving on the surface of a frictionless horizontal table. The wire is 3.14 m long and has a radius of 1.72 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
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 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 =...
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...
When subjected to a force of compression, the length of a bone (compression Young's modulus 9.4 x 109 N/m2, tensile Young's modulus 1.6 x 1010 N/m2) decreases by 1.8 x 10-5 m. When this same bone is subjected to a tensile force of the same magnitude, by how much does it stretch?
