The kinetic sculpture requires that each of the three pinned beams be in perfect balance at all
Question:
The kinetic sculpture requires that each of the three pinned beams be in perfect balance at all times during its slow motion. If each member has a uniform weight density γ and length L, determine the necessary counterweights W1, W2 and W3 which must be added to the ends of each member to keep the system in balance for any position. Neglect the size of the counterweights.
Given:
γ = 2lb/ft
L = 3 ft
a = 1 ft
