The discussion revolves around the analysis of forces acting on an elevator in a free body diagram context, specifically focusing on the forces to consider when the elevator is accelerating upwards.
Some participants affirm the original poster's approach of considering Ft greater than Fg when the elevator is accelerating upwards. However, there is also a reminder that the elevator's motion could vary, prompting further examination of the assumptions made regarding acceleration.
The original poster's question is based on a specific scenario where the elevator is stated to be accelerating, which influences the forces considered in the free body diagram.
In that case, your diagram is correct to have Ft greater in magnitude than Fg, since Ft + Fg = Fnet = ma and a must be non-zero, and I'm assuming the elevator is accelerating in the direction of Ft. ;)dranseth said:Well, in the question it stated that it was accelerating... So was I right to have only the two forces Ft and Fg with Ft bigger?
