A 500 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, 15 degrees below horizontal, with 500 N of tension. Ellen's rope pulls toward the right, 25 degrees below horizontal.
What tension must Ellen maintain in her rope to keep the piano descending at a steady speed? (a=0)
What is the tension in the main cable supporting the piano?
