Unformatted text preview: A , B , and C . Present your answers by showing the forces on member ABCD given below. 1000 lb 633 lb 2000 lb 633 lb 600 lb 600 lb 3. (25%) The member is supported by a pin at A (Note: reactions at A are Ay , Ax , Az , My , and Mz ) and cable BC . If the load at D is 300 lb , determine the x , y , and z components of the reaction at A and the tension in cable BC . ( Note: possible reactions at A are A y , A x , A z , M y , and M z ) FBD Solving system of equations: 4. (30%) For the truss and loading shown: (a) Identify all zero force members. (b) Determine the forces in members AL , AB , IJ , EI , and EF (Indicate whether the members are in tension or compression). Member Force (kN) T or C AL AB IJ EI EF cut line joint Support reactions: C T C T T 17.22 13.78 12.9 6.67 12.9 Zero Force Members: LB; JD; HF...
