![## Problem Description
A 240-kg uniform rectangular plate is supported in the position shown in the figure by hinges A and B and by a cable DCE that passes over a frictionless hook at C. Assume that the tension is the same in both parts of the cable and that hinge B does not exert any axial thrust.
### Diagram Explanation
The diagram illustrates a rectangular plate positioned horizontally. It is supported by two hinges, labeled A and B, which are attached to the underside of the plate. There is also a cable labeled DCE, creating tension support at three points: D, C, and E.
### Dimensions and Positions
- The plate is positioned within a 3D coordinate system with x, y, and z axes.
- Length from hinge A to the edge of the plate in the z-direction is 90 mm.
- Total length in the x-direction from C to the end of the plate is 690 mm.
- The plate extends 90 mm from hinge B to its edge in the z-direction.
- Cable DCE distances:
- CD is 450 mm from point A.
- CE is 675 mm in the x-direction from point A.
- Cable positions:
- D is directly above the plate, 960 mm from AC in the x-direction.
- E is also above the plate, 675 mm from AB in the x-direction.
### Task
Draw the free-body diagram required to determine the tension in the cable. Note that the cable DCE acts as a single cable.
### Key Considerations
- Center of mass located at the center of the plate, given it's a uniform rectangular plate.
- Since points D, C, and E are connected by a cable, the tension throughout the cable is consistent.
- Assume that hinge B exerts no axial thrust, simplifying calculation of forces.
This problem requires understanding moments, forces, and equilibrium in three dimensions, as well as interpreting spatial diagrams for mechanical systems.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fffc9e826-c865-4bea-8e1f-6dcccd31bfb0%2F5584ba64-fcc0-450d-8d1d-e7a49492d3dc%2Fenxf0sj.png&w=3840&q=75)
