Homework Statement
An elevator containing 3 passengers(with a mass of 72kg 84 kg and 35 kg) has a mass combined of 1030 kg . The cable attached to the elevator exherts an upward force of 12000 N. But the friction opposing the motion of the elevator is 1400 N.
a) Draw a free body diagram for all the forces acting on the elevator.
Homework Equations
Fg=mg
The Attempt at a Solution
Now since net force is greater for upward motion, we can assume the elevator is going up, since gravity + friction is still less than the upward force exherted, so elevator is going up,
but my question is...in the free body diagram..do i put both friction and force of gravity as a downward force?
Or should i just remove force of gravity and just put force of friction in the freebody diagram as a downward force?
The free body diagram i have in mind is in attachment, and that's what it looks like now...as always you don't need to download attachment to view it.
thanks!
