Shown is a simply supported beam loaded by a force at A, a couple at C, and a distributed load from D to E. We plan to remove the moment at C and replace it with a couple consisting of forces applied at B and E. 30 lb/ft 20 lb 20 lbft A Z B D E C 0.5 ft 0.5 ft 0.5 ft 0.5 ft || What is the magnitude of the couple that replaces the removed couple moment? Your favorite omega-shaped loop consists of two curved members AB and BC pinned at A, B, and C, comprising a small half-loop. The pin at B is loaded by a horizontal force of 120 lb. 120 lb 4 in A - 3 in + 3 in What is the reaction force magnitude at A? [2 pts] C
