Question 1.
What is shear traction?
Show hintHide hint
Think about how forces apply along surfaces.
Question 2.
Define normal component of traction.
Show hintHide hint
Look for the force acting directly away or towards the surface.
3Question 3.
What is the shear component of traction?
- Acts perpendicular to the surface
- Acts parallel to the surface
- Is irrelevant to traction analysis
Show hintHide hint
Think about traction direction relative to surfaces.
4Question 4.
Are principal planes oriented at 90 degrees to the axis?
- True
- False
Show hintHide hint
Recall the derivation showing principal directions.
Question 5.
Derive the shear component of traction on an arbitrary plane from first principles, using appropriate illustrations.
Show hintHide hint
Use vector decomposition principles.
Question 6.
