We provide Insights into distributed torsional loading.

Su2023 Live Session 10: Torsion II focusing on distributed torsional loading (starts from 1:42:24)
Date: June 8, 2023
Note: At the very end of this live session, we discuss a more careful approach to solving for angle of twist with a distributed torque than during Sp2023.
