Três elementos formam a treliça da fig. abaixo. O nó A é forçado a se mover pelo bloco deslizante apenas na direção horizontal. Todos os elementos tem a mesma seção transversal A = 400 mm2 e o módulo de elasticidade é E = 70 GPa para todos os elementos. (a) Determine a carga horizontal P que seria necessária para mover o nó A para a direita, em 5 mm. (b) Determine as forças nos elementos F1, F2 e F3 devidas à carga P. (c) Determine a reação vertical entre o bloco em A e a pista na qual ele se desloca.
