1.5 m D -1.5 m C -1.5 m 4 kN B Group Problem 4.2.1 The 4kN load at B of the beam is supported by pins at A and C. Find the support reactions at A and C.

3. For the loaded beam shown below, solve for the reactions at point A (a roller) and point B (a pin joint). 30 KN 3 m + 1 m 4 m 3

Problem 4.1 - Beam AB is supported by a ball-and-socket at point A and guy wires FC and ED. Find a) the components of the reaction at support A (RAX, RAY, & RAZ) and b) the forces in the guy wires (TED & TFC). 1 m D 4 r m C 3 m 2 m A E F BA 2 m 2 m 50 kg 3 m
