Dockside lifting. The figure below shows the cable rigging for a crane to lift a large container with mass 3.45 x 10# kg onto or from a ship. Assume that the mass is uniformly spread within the container. The container is supported at its corners by four identical cables that are under tension T4 and that are at an angle 04 = 58.8 with the vertical. They are attached to a horizontal bar that is supported by two identical cables under tension T2 and at angle 02 = 37.2 with the vertical. They are attached to the main crane cable that is under tension 71 and vertical. Assume the mass of the bar is negligible compared to the weight of the container. What are the values of (a) T1, (b) T2, and (c) T4? Main cable Horizontal bar Worldwide Shipping
