W1 F1 F2 A D 2.0 m L2 1.0 m A beam is supported by a pin connection at B and a roller support at D. An upwards force F1 =1.8 kN acts at the left end of the beam (point A). A rightwards force F2 =25 kN acts at the right end of the beam (point E). A uniformly distributed load wi =2.6 kN/m pushes down on the beam between points C and E. The separation between A and B is L1 =0.6 m , and the separation between C and D is L2 =1.4 m .
A beam is supported by a pin connection at B and a roller support at D. An upwards force F1=F1=1.8 kNkN acts at the left end of the beam (point A). A rightwards force F2=F2=25 kNkN acts at the right end of the beam (point E). A uniformly distributed load w1=w1=2.6 kN/mkN/m pushes down on the beam between points C and E. The separation between A and B is L1=L1=0.6 mm , and the separation between C and D is L2=L2=1.4 mm .
