Class XI

Bulk modulus is
  1. the ratio of hydraulic stress to the corresponding hydraulic strain
  2. the ratio of longitudinal stress to the corresponding hydraulic strain
  3. the ratio of lateral stress to the corresponding hydraulic strain
  4. the ratio of hydraulic strain to the corresponding hydraulic stress
Young’s modulus Y is
  1. the ratio of tensile (or compressive) stress (σ)(σ) to the longitudinal strain (ε)
  2. the ratio of shear strain (θ)(θ) to the longitudinal stress (σ)
  3. the ratio of shear stress (σ)(σ) to the longitudinal strain (θ)
  4. the ratio of longitudinal strain (ε)(ε) to the tensile (or compressive) stress (σ)
In constructing a large mobile, an artist hangs an aluminum sphere of mass 6.0 kg from a vertical steel wire 0.50 m long and 2.5 ×× 10−310−3 cm2cm2in cross-sectional area. On the bottom of the sphere he attaches a similar steel wire, from which he hangs a brass cube of mass 10.0 kg. Compute the elongation.
  1. 1.7 mm upper, 1.0 mm lower
  2. 1.5 mm upper, 1.1 mm lower
  3. 1.6 mm upper, 1.0 mm lower
  4. 1.4 mm upper, 1.0 mm lower
Stress is
  1. total applied force
  2. force per unit length
  3. three point average of forces
  4. force per unit area
Columns are loaded in
  1. tension
  2. compression
