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...
