Power Cruise
How do i calculate power in this problem?
A 650 kg elevator starts from rest. it moves upward for 3.00 s with constant acceleration until it reaches its cruising speed of 1.75 m/s.
What is the average power of the elevator motor during this time interval?
How does this power compare with the motor power when the elevator moves at its cruising speed?
Power = Work/time
Work = force x distance
in the first case, the force exerted = F =ma
if the elevator started from rest and got to a speed of 1.75 m/s in 3 secs, then its accel was 1.75m/s / 3s = 0.58m/s/s
then the force acting on the elevator is found from newton’s second law:
sum of forces = ma
sum of forces = tension pulling up elevator – mg = ma
tension force on elevator = m(g+a) = 650kg(9.8+0.58)m/s/s
= 6747N
the distance the elevator travels in 3 seconds is:
dist = 1/2 at^2 = 0.5(0.583)3^2 = 2.62 m
the power = force x distance/ 3 s = 5892.4 Watts
in the second case, the power is NOT zero (wouldnt it be a wonderful world if we could run machines at constant speed and not do work)
Power = Work/time = Force x distance /time; but notice that we have a distance/time term, which we know to be velocity
in the case of constant motion, we have that Power = Force x velocity
here the force pulling up the elevator is equal to the weight of the elevator = mg = 6370N
so power = 6370N x 1.75m/s = 11,147.5 W
the power output is greater at constant speed, since the elevator is traveling faster during cruising compared to the acceleration phase
