A 600 kg piano is being lowered into position by a crane while two people steady it with ropes pulling to the sides. Bob's rope pulls to the left, 14" below horizontal, with 400 N of tension. Ellen's rope pulls toward the right, 25" below horizontal. What tension must Ellen maintain in her rope to keep the piano descending at a steady speed?
What is the tension in the vertical main cable supporting the piano?
