A cargo ship is loading using a boom crane, which is a 15 m long pole with a cable for lifting cargo which is suspended from the end of the pole. The boom is raised via a cable attached at a point that is 2/3 of the distance to the end of the pole. At one point the crane is lifting an 900 kg crate with the pole making a 30 degree angle with the horizontal, while the cable makes a 40 degree angle with the horizontal. Estimate the tension on the cable.
