6 sample questions

Question 1.
What does the angle of twist represent?
Show hintHide hint
Think about what happens to a shaft when you apply a force to it.
Question 2.
What is the formula for angle of twist?
Show hintHide hint
Remember the acronym TL-G-J!
3Question 3.
What is the angle of twist formula?
- θ = TL/GJ
- θ = T/GJ
- θ = TL^2/G
Show hintHide hint
Look for the equation that includes torque and length in the numerator.
4Question 4.
True or False: The angle of twist increases with the length of the shaft.
- True
- False
Show hintHide hint
Consider what happens as more material is added.
Question 5.
A steel shaft with a diameter of 0.05 m and length of 2 m has a shear modulus of 80 GPa. If a torque of 150 Nm is applied, calculate the angle of twist and discuss how changing the diameter affects the outcome.

Remember to deal with unit conversions if necessary.
Question 6.
Design a system with a hollow shaft that connects two gears. If the outer diameter is 0.1 m and the inner diameter is 0.06 m with a length of 1.5 m, how would you determine the required torque if the desired angle of twist is limited to 0.02 radians?
