Which row in the table correctly compares the magnitude of the support force exerted on the right end of the beam, the magnitude of the total force exerted by the hinge on the beam, and the direction of the horizontal component of the force exerted by the hinge on the beam in Case 2 relative to Case 1?
| Support Force Magnitude in Case 2 | Total Hinge Force Magnitude in Case 2 | Direction of Horizontal Hinge Force in Case 2 | |
|---|---|---|---|
| (A) | Greater than in Case 1 | Greater than in Case 1 | Away from the wall |
| (B) | Equal to Case 1 | Equal to Case 1 | Toward the wall |
| (C) | Equal to Case 1 | Less than in Case 1 | Away from the wall |
