An elevator is pulled upward so it moves with increasing upward
speed?the force exerted by the cable on the elevator is constant
and greater than the downward gravitational force exerted by Earth.
When the elevator is moving up medium-fast, the force exerted by
the cable on the elevator changes abruptly to just balance the
downward gravitational force of Earth?the sum of the forces that
the cable and Earth exert on the elevator is now zero.

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...

One kind of elevator has the elevator car hanging from a cable,
which then passes over a pulley and connects to a counterweight, as
shown in (Figure 1). The mass of a fully-loaded elevator (that is,
the elevator and all its passengers) is 1850 kg , the mass of the
counterweight is 1500 kg , and the pulley has a radius of 0.4 m
and a mass of 400 kg . A motor drives the motion of the elevator by...

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.
