Question:
Three stage lights are mounted on a pipe as shown. The mass of each light is 1.8 Ma = mB= kg and mC = 1.6 kg.
(a) If d = 0.75 m, determine the distance from D to the line of action of the resultant of the weights of the three lights.
(b) Determine the value of d so that the resultant of the weights passes through the midpoint of the pipe.
