Find the forces at points A, B, and C for the landing gear of the figure shown & the torsion T about O. Members OB and OC are two-force members. Member OA resists bending and torsion, but point A is hinged by a universal joint so that the member can carry torsion but no bending in any direction at this point. Reaction at A will produced a couple T about O. (Choose all correct answers) * T = 4800 in-lb B = 1206 lb C = 1206 lb C = 4800 lb B = 6000 lb T= 6000 in-lb T = 1120 in-lb A = 1206 lb C = 6000 lb B = 6060 lb A = 1120 lb A = 4800 lb 1000 1000 4,000 lb 30. -20% K 4,000 lb
