Challenge Problems
Push your limits with advanced challenges
A rectangular beam with dimensions 0.05 m x 0.1 m is subjected to a torque of 150 Nm. Calculate the polar moment of inertia and the torsional energy stored if the length of the beam is 1.5 m and shear modulus is 60 GPa.
💡 Hint: Make sure to compute J correctly to proceed with energy calculations.
Design a cylindrical shaft to carry a specific torque of 300 Nm without exceeding a shear stress limit of 50 MPa. What is the minimum diameter required?
💡 Hint: This involves rearranging the formula to isolate the diameter. Be sure to also remember how to convert units properly.
