An electric elevator with a motor at the top has a multistrand cable weighing 8.4 lb/ft. When the car is on the first floor 270 feet of cable are paid out, and effectively 0 feet when the car is on the top floor. How much work does the motor do to lift an 1800 lb car and cable from the first floor to the top? Provide a picture model, give the approximate equation, then solve.
2: Find the acceleration of the three weights shown in fig. Assume pulleys are frictionless. Also find the tension in the cables. 200 N 40 N 60 N
A hydraulic car list has an actual mechanical advantage of 50. The mechanic using it applies a force of 48N to on the handle and lifts a car 1.5m off the shop floor.
How much does the car weigh?
