The system below is at equilibrium. The crane arm BD has a mass of 5000 kg and a centre of mass at G1. The crane arm BC has a mass of 2000 kg and centre of mass at G2. Determine the mass of the counterweight at point C so that the net moment around point A is zero.

14 marks) The system below is at aquilibrium. The crane arm BD has a mass of 5000 kg and a centre of mass at (31. The crane arm BC has a mass of 2000 kg and cantra of mass at 32. Datarmina the mass of the counterweight at point E so that the nat moment around point A is zarn. For full marks you need to show some worki m = ? 3.00 m G 6.00 m 20.0 m 8.00 m 10.0 m G 1000 kg
