A fully loaded, slow-moving freight elevator has a cab with a total mass of 1300 kg, which is required to travel upward 47 m in 3.5 min, starting and ending at rest. The elevator's counterweight has a mass of only 800 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?
Chapter 07, Problem 049 A fully loaded, slow-moving freight elevator has a cab with a total mass of 1800 kg, which is required to travel upward 45 m in 4.7 min, starting and ending at rest. The elevator's counterweight has a mass of only 860 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable? Number the tolerance is +/-3% Units
The loaded cab of an elevator has a mass of 2.50 × 103 kg and moves 205. m up the shaft in 26.0 s at constant speed. At what average rate does the force from the cable do work on the cab?
The loaded cab of an elevator has a mass of 3.0 103 kg and moves 240 m up the shaft in 23 s at constant speed. At what average rate does the force from the cable do work on the cab?
A certain elevator cab has a total run of 199 m and a maximum speed is 307 m/min, and it accelerates from rest and then back to rest at 1.11 m/s-. (a) How far does the cab move while accelerating to full speed from rest? (b) How long does it take to make the nonstop 199 m run, starting and ending at rest? (a) Number (b) Number Units Units
An elevator has mass 600 kg, not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 20.0 m (five floors) in 16.0 s, and it is driven by a motor that can provide up to 40 hp to the elevator. A. What is the maximum number of passengers that can ride in the elevator? Assume that an average passenger has mass 65.0 kg.
An elevator has mass 650 kg , not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 21.0 m(five floors) in 16.7 s , and it is driven by a motor that can provide up to 44 hp to the elevator. What is the maximum number of passengers that can ride in the elevator? Assume that an average passenger has mass 65.0 kg.
A laboratory freight elevator, including its load, has a mass of 500 kg. It is prevented from rotating by the track and wheels mounted along its sides. The elevator is used to carry highly sensitive equipment so it cannot exceed an acceleration of 3 m/s2 . A geared motor is used with the cable/pulley system shown below to raise and lower the elevator. The motor turns gear A with a constant angular acceleration, αA. The gears of the motor have...
