Rock Mechanics Exam Questions with 100%
Correct Answers 2024
pressure - Correct Answers-force per unit area applied to solid by a load
stress* - Correct Answers-pressure transmitted from the external face to an internal
location (force per unity area)
types of stress* - Correct Answers-1) compressive
2) tensile
3) shear
compressive stress* - Correct Answers-stresses of equal magnitude that act toward a
point from opposite directions
tensile stress* - Correct Answers-stresses of equal magnitude that act away from a
point
shear stress* - Correct Answers--stresses that are offset from one another and act in
opposite directions
-act parallel to plane
three principle stresses* - Correct Answers-1) maximum
2) intermediate
3) minimum
Mohr's Circle* - Correct Answers-graphical representation of shear and normal stresses
on inclined planes
strain* - Correct Answers-amount of deformation
=change in L/L
type and amount of strain depends on* - Correct Answers-1) type of stress
2) depth and temperature
3) strain rate
ideal materials* - Correct Answers-1) elastic
2) viscous
3) plastic
elastic materials* - Correct Answers--linear regression on stress strain plot
-strain is recoverable
-solids
modulus of elasticity* - Correct Answers-slope of regression line of elastic materials
=stress/strain
viscous materials* - Correct Answers--linear regression in stress strain plot
-fluids
viscosity* - Correct Answers-slope of regression line of viscous materials
plastic materials* - Correct Answers--no strain until some critical stress value is reached
-continuous deformation after this point
