Show hintHide hint
Consider forces acting at the boundaries.
Question 2.
Explain what the stress tensor represents.
Show hintHide hint
Think about how stress is distributed in three dimensions.
3Question 3.
What is traction?
- Internal forces acting at surfaces
- External forces applied to the body
- Gravity's effect on the mass
Show hintHide hint
Focus on what happens inside a material when loads are applied.
4Question 4.
True or False: The stress tensor can vary with position within a body.
- True
- False
Show hintHide hint
Think about how stress distributes differently at various points.
Question 5.
A cuboidal beam of dimensions 2m x 1m x 1m is subjected to a uniform load of 500N across one face. Calculate the traction force acting on that face.
Show hintHide hint
Use the definition of traction to guide your calculations.
Question 6.
Given a cuboid with varying traction calculated as σ(x) = 3x² + 2x + 1, determine the total traction force on a face from x=0 to x=2 using integration.
