Question 1.
Define shear stress and shear force.
Show hintHide hint
Think of how forces act when bending a beam.
Question 2.
What is the purpose of the moment of inertia in beam theory?
Show hintHide hint
Consider how this impacts the shape and loading of a beam.
3Question 3.
What does shear stress (τ) depend on for beam cross-sections?
- Material type
- Shear force and geometry
- Applied loads
Show hintHide hint
Think about the factors that affect how beams bend and carry load.
4Question 4.
True or False: Shear stress in a circular beam is constant at all points.
- True
- False
Show hintHide hint
Reflect on circular shapes and how loads are distributed.
Question 5.
Given an I-beam with a total shear force of 500 N, width at the flanges = 150 mm, and height = 300 mm, calculate the shear stress at the neutral axis.
Show hintHide hint
Carefully compute the moment of inertia based on A and b values.
Question 6.
Analyze the shear stress variation for a circular beam of diameter 200 mm and total shear V = 600 N. How would you determine τ at different radial positions?
Show hintHide hint
Focus on understanding shear at centroid vs. outer radius.
