An electric elevator with a motor at the top has a multistrand cable weighing 4 lb/ft. When the car is at the first floor, 150 ft of cable are paid out, and effectively 0 ft are out when the car is at the top floor. How much work does the motor do just lifting the cable when it takes the car from the first floor to the top? The amount of work required is ft-lb. (Simplify your answer.)
11. Lifting an elevator cable An electric elevator with a motor at the top has a multistrand cable weighing 4.5 lb/ft. When the car are out when the car is at the top floor. How much work does the is at the first floor, 180 ft of cable are paid out, and effectively 0ft motor do just lifting the cable when it takes the car from the first Aoor to the top?
_________An elevator suspended by a vertical cable is moving downward but slowing down. The tension in the cable must be A) greater than the weight of the elevator. B) less than the weight of the elevator. C) equal to the weight of the elevator. ______ A bucket is being lowered by a very light rope with a constant downward velocity. The tension in the rope must be A) equal to the weight of the bucket. B) greater than the weight...
A 920 kg elevator is suspended by a vertical cable. The elevator is accelerating down at 1.1 m/s2. What is the tension in the cable? Express your answer in newtons and round to the nearest whole number.
An elevator suspends from a verticle cable and the elevator accelerates upward. is the tension in the cable a. greater than the elevators b. lower than the elevators c. the same d. cannot be determined what about if it was accelerated downwards?
QUESTION 24 An elevator of total mass 200 kg is supported by a single cable, as shown in the diagram. What will the tension in the cable be if it accelerates upwards at rate of 2.37 m/s2, in units of newtons? -Cable Elevator QUESTION 25 An object moves in a horizontal circle of radius 2.50 m at a speed of 27.1 m/s. What is the centripetal acceleration of the object, in units of m/s2?

An oil pipeline is supported at 6-ft intervals by vertical hangers attached to the cable shown. Due to the combined weight of the pipe and its contents the tension in each hanger is 400 lb. Knowing that, do 10 ft determine (a) the maximum tension in the cable, (b) the distance de dsdcdp -5 @ 6 ft = 30 ft Adidation
A single mass m1 = 3.5 kg hangs from a spring in a motionless elevator. The spring is extended x = 15 cm from its unstretched length. 1) What is the spring constant of the spring? Now, three masses m1 = 3.5 kg, m2 = 10.5 kg and m3 = 7 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. What is the force the top...
