Question

You are working on the design of a crane (a lifting device) to move large storage containers. In your design report, a free body diagram for the container is needed as it moves upwards and slows down. Your co-workers from the University of Texas don?t understand much physics so they bring their diagrams to you. Which one is most nearly correct? The relative sizes of the arrows should be qualitatively correct (larger force gets longer arrow). The force labels are poor, but don?t worry about that now. Neglect air resistance.

Explanation / Answer

the fourth one with Ftension larger than the Fgravity is the correct one
