## Solution to Problem 340 | Torsion of thin-walled tube

Problem 340
A tube 2 mm thick has the shape shown in Fig. P-340. Find the shearing stress caused by a torque of 600 N·m. ## Solution to Problem 339 | Torsion of thin-walled tube

Problem 339
A torque of 450 lb·ft is applied to the square section shown in Fig. P-339. Determine the smallest permissible dimension a if the shearing stress is limited to 6000 psi. ## Solution to Problem 338 | Torsion of thin-walled tube

Problem 338
A tube 0.10 in. thick has an elliptical shape shown in Fig. P-338. What torque will cause a shearing stress of 8000 psi? ## Solution to Problem 337 | Torsion of thin-walled tube

Problem 337
A torque of 600 N·m is applied to the rectangular section shown in Fig. P-337. Determine the wall thickness t so as not to exceed a shear stress of 80 MPa. What is the shear stress in the short sides? Neglect stress concentration at the corners.
