The maximum allowable compression in members ab and ac is 3.2 kn, and the maximum
The maximum allowable compression in members ab and ac is 3.2 kn, and the maximum allowable tensile force in cable ad is 3.2 kn. find the maximum mass, w, such that none of the members or cables exceed their maximum allowables, given: l1 = 8 m, l2 = 4 m, l3 = 10 m, l4 = 8 m
