A lift cage has a mass of 800kg. Determine the tension in the lifting cable when the cage is ascending with uniform velocity
When the lift cage is ascending with uniform velocity, the net force acting on the cage is zero. This means that the tension in the lifting cable is equal in magnitude to the weight of the lift cage.
The weight of the lift cage can be calculated using the formula:
Weight = mass x gravity
Weight = 800kg x 9.8 m/s^2
Weight = 7840 N
Therefore, the tension in the lifting cable is 7840 N.
