3.5 Steering column mount The steel steering column mounting bean extends from side to side with end conditions unconstrained for warping. A torque is applied to the beam at the steering column location. a) Determine rotation at the point of load application under 0.5 kNm torque with a closed section. b) Determine the rotation at the point of load application under 0.5 kNm torque when the section contains narrow slit (unrestrained warping). 1.4 m 0.4m CED Torque applied by steering column mount 100 mm equilateral triangle 1.5 mm thick (a) A. Narrow slit (b) Exercise 3.5
