Question:

Hard math question?

You work at an industrial train platform and are operating two cranes to lift a 3000 lb train carDue to a limited budget, your crane cables have different maximum tensions: the left crane can hold 2000 lb of tension, but the right crane can only hold 1500 lb of tensionThe cranes are currently positioned so that the left cable makes a 55° angle with the horizontal top of the train car, and the right cable makes a 75° angleWhen the platform below the car is removed and its weight is applied, how much tension will each cable have in this position? Will the cables snap? To what angle could you adjust the left cable so that both cranes can lift the 3000 lb train car?
