PROBLEM: a lift motor has 2 move a fully laden lift 4m between floors in 1.5s. the lift has a mass of 1850kg(i

[From: ] [author: ] [Date: 13-08-22] [Hit: ]
what is the upward force in the cable when the lift is moving at a constant speed?c. what is the work done by the motor?-a. Wt = m*g = 1850*9.81 = 18.......
PROBLEM: a lift motor has 2 move a fully laden lift 4m between floors in 1.5s. the lift has a mass of 1850kg(ignore friction)

a. calculate the weight of the fully laden lift.
b. what is the upward force in the cable when the lift is moving at a constant speed?
c. what is the work done by the motor?

-
a. Wt = m*g = 1850*9.81 = 18.1*10^3 N
b. 18.1*10^3 N
c. W = F*s 18.1*10^3*4 = 72.6 kJ

-
18.1*10^3 N??
