							(a) The weight of the elevator in S.I units is:
234-2418_1.PNG
To calculate the mass of elevator divide the magnitude weight of the elevator by the magnitude of acceleration due to gravity,
234-921_1.PNG
Therefore the tension in the elevator when it is moving with upward acceleration is 30,836.2 N .
234-2004_1.PNG
Therefore the tension in the elevator when it is moving upward but with downward acceleration is 24,323.8 N .
