include one problem related to Electrical Engineering AND one problem related to
Mechanical or Thermal Engineering.
A freight elevator, including its load, has a mass of 1 Mg. It is prevented from rotating due to the track and wheels mounted along its sides. The motor M develops a constant tension T= 4.1 kN in its attached cable. Neglect the mass of the pulleys and cables.
Write out the equations of motion for the elevator, and solve for the acceleration.
Then apply the constant acceleration equations to solve for the velocity when the elevator has moved 4 m upward from rest.
