# PHYSICS : REVISION TEST ON TOPICS OF CLASS XI ---VIII

Which amongst the following substances, is most elastic?
brass
glass
rubber
steel
The deformation per unit length in the direction offload is called
lateral strain
shear strain
linear or longitudinal strain
volumetric starin
A shaft of diameter d and length l has been loaded axially. The ratio of change in diameter to the original diameter is known as
longitudinal strain
shear strain
volumetric strain
lateral strain
Stress represents the
external force acting on the body
pressure setup with in the body material
force by which the material of the body oppose the deformation
resistance per unit area to deformation by internal forces
A circular bar has been subject to compressive load resulting into a decrease in length and a simultaneous increase in diameter. The ratio of strain in the diameteral direction to that in the longitudinal direction is referred to as
Hook’s ratio
Euler’s ratio
Poisson’s ratio
Modulus of elasticity
Which of the following materials is expected to have the least value of Young’s modulus of elasticity?
wood
copper
glass
aluminum
Measurements have been made for the Young’s modules of elasticity for mild steel specimen both in tension and compression. The ratio Et/Ec will be approximately equal to
0.5
0.75
1.0
1.25
Young’s modulus of elasticity for a perfectly rigid body is
zero
unity
infinity
some finite non-zero constant
Dimensional formula for Young’s modulus of elasticity is
ML-1T-2
MLT-2
M-1L-1T-1
ML-2T-2
Modules of elasticity is defined as the ratio of
axial stress to lateral strain
axial stress to axial strain
lateral strain to longitudinal strain
axial stress to volumetric strain
