Question 1.
What does the term torsion refer to?
Show hintHide hint
Think about twisting forces applied to different materials.
Question 2.
What is the formula for calculating shear stress in a solid shaft?
Show hintHide hint
Identify the variables in the formula related to torque, radius, and moment of inertia.
3Question 3.
What is the formula for shear stress in a solid circular shaft?
- τ = T*r/J
- τ = J*T*r
- τ = T^2/r
Show hintHide hint
Remember 'T', 'r', and the importance of 'J' in the formula.
4Question 4.
True or False: Higher torque increases the angle of twist in a shaft.
- True
- False
Show hintHide hint
Think about what happens when more force is applied.
Question 5.
A solid circular shaft with a diameter of 0.15 m is subject to a torque of 300 Nm. Calculate the maximum shear stress.
Show hintHide hint
Remember to compute J accurately.
Question 6.
A shaft made of steel with a shear modulus of 200 GPa and length of 5 m is twisted with a torque of 400 Nm. Find the angle of twist.
Show hintHide hint
Ensure G is converted to the same unit system used in other values.
