Question
The truss shown is the canopy of the bleachers of an open stadium. It is idealized that the support at A is hinge and at B is roller. Considering the uniformly distributed load w, and given the following:
w = 25 kN/m H1 = 0.5 m H2 = 1.2 m H3 = 0.8 m H4 = 1.2 m a = 0.8 m L1 = 1.1 m L2 = 3 m
Neglect the self-weight of the canopy. Calculate the following: (for member forces, indicate if in compression or tension)
1. Reaction at A, in kN.
2.Reaction at B, in KN.
3.Force in DE, in kN
4.Force in DF, in kN.
5.Force in CF, in KN.
