Question

Which of the objects below is in static equilibrium? 

The image consists of four diagrams demonstrating different loading conditions on beams. Each diagram includes a rectangular beam with arrows indicating the direction of the loads applied.

### Top-Left Diagram
A vertical beam is subject to horizontal forces. 
- Arrows point towards the beam from the left and right sides, indicating forces applied horizontally.

### Top-Middle Diagram
Another vertical beam with both a horizontal and vertical load.
- An arrow points horizontally from the left to the middle of the beam.
- Another arrow points vertically down from the top end of the beam.

### Top-Right Diagram
A horizontal beam supported at both ends with a central downward load.
- Two arrows point upwards at the ends of the beam, indicating support reactions.
- A single arrow points downwards at the center, representing the applied load.

### Bottom-Left Diagram
A horizontal beam supported at both ends with a central upward load.
- Two arrows point upwards at the ends, indicating support reactions.
- An arrow points upwards at the center, indicating the applied load in the opposite direction of the usual gravitational force.

In all diagrams, a small symbol resembling a blue square represents the location of possible points of interest or failure.
