2 cards from this section. Quick, good the night before a test.
Define shear stress in the context of torsion.
Think about internal forces in circular shafts.
What is the formula for torque?
Consider the definition of rotational force.
What does τ represent in shear stress calculations?
Think about the force per unit area.
True or False: The angle of twist is independent of shaft length.
Recall how length affects torque effects.
A solid shaft subjected to a torque of 300 Nm twists by 1.5 radians. What is the length of the shaft given J = 2 x 10^-6 m^4 and G = 79 GPa?
Rearrange the equation wisely.
Two helical springs have different diameters and are subjected to the same axial load. If one spring has a larger mean coil diameter, which spring will experience more shear stress?
Relate diameter to stress in your reasoning.
