27. (a) We note that the angle between the cable and the strut is α = θ φ = 45º – 30º = 15º. The angle between the strut and any vertical force (like the weights in the problem) is β = 90º – 45º = 45º. Denoting M = 225 kg and m = 45.0 kg, and A as the length of the boom, we compute torques about the hinge and find () 2 sin sin sin sin / 2 . sin sin Mg mg Mg mg T ββ αα + + == A A A The unknown length
