Apparently the lower end of the girder is not free to slide along the ground. Maybe it's digging into the ground or perhaps, it's prevented from sliding to the left by some obstruction.question dude said:

A force is a push or pull acting on an object. It can cause an object to accelerate, decelerate, change direction, or change shape.
Equilibrium occurs when all forces acting on an object cancel each other out, resulting in a state of balance. This means that the object will either remain at rest or continue to move at a constant velocity.
To calculate net force, you must first determine all the individual forces acting on an object. Then, use the equation Fnet = ma, where Fnet is the net force, m is the mass of the object, and a is the acceleration. This will give you the overall force acting on the object.
A balanced force occurs when all forces acting on an object are equal in magnitude and opposite in direction, resulting in a state of equilibrium. An unbalanced force, on the other hand, occurs when the forces are not equal and the object will experience a change in motion.
The direction of a force can determine whether an object is in a state of equilibrium or not. When all forces are acting in the same direction, the object will continue to move at a constant velocity. When forces are acting in opposite directions, the object will either accelerate or decelerate depending on the magnitude of the forces.
