CELEC 5 MOD 1

The Shear stress, σv, acts on the horizontal plane at shallow depth h.

• TRUE

• FALSE

Vertical rock beams can be dangerous because of the weak tensile strength.

• TRUE

• FALSE

Stresses that are offset from one another and act in opposite directions.

• Shear

• Normal

• Axial

• Compressive

No strain until some critical stress value has been reached; Then continuous deformation

• Strain

• Rupture

• Plastic

• Elasticity

It is the pressure transmitted from the external face into the internal location within a body.

• Load

• Pressure

• Stress

• Strength

The amount of deformation is called .

• Rupture

• Linear

• Strain
