• Bending

A torque wrench is used to measure how much force is applied to a bolt to ensure the bolt is not over stretched. What force does it measure?

• Compression

• Tension

• Torsion

• Shear

Which parameter is not related angle of twist?

• Member's length

• Polar moment of inertia

• Shear modulus

• Elastic modulus

What is the form of displacement due to torsion?

• Axial strain

• Shear strain

• Elongation

• Contraction

If the angle of twist is small, the length of the shaft and its radius will remain unchanged.

• True

• False

The shear strain, γ is zero at the outer boundary and reaches maximum γ_max at the axis of the shaft.

• True

• False

τ will vary from zero at the shaft’s longitudinal axis to a maximum value, τ_max at its outer surface.

• True

• False
