Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The potential energy is the measure of the net work done by or on the body. The spring potential energy is the potential energy stored due to the deformation of an elastic spring and this elasticity is due to the stretched spring. The elasticity is the ability of a solid-state matter to come back to its equilibrium position or original position after any kind of external force is acted on it. It is also known as Elastic potential energy. The potential energy here is caused due to the displacement of the spring from its equilibrium position to another position and this potential energy is equal to the net work done due to the stretching of the spring. It also resembles the same mechanics of the oscillation of a simple pendulum, where due to the external force, the object moves from its equilibrium position to its maximum ends and the periodic motion continues till it comes back to the equilibrium position to rest. 

Question

**Problem Statement:**

A 2.50-kg uniform bar of length \( \ell = 1.30 \, \text{m} \) is held in a horizontal position by three vertical springs as shown in the figure. The two lower springs are compressed and exert upward forces on the bar of magnitude \( F_1 = 6.10 \, \text{N} \) and \( F_2 = 9.60 \, \text{N} \), respectively.

**Tasks:**

(a) Find the force \( F_s \) exerted by the top spring on the bar.
- Answer in N downward

(b) Find the location \( x \) of the upper spring that will keep the bar in equilibrium.
- Answer in cm

**Diagram Explanation:**

- The diagram shows a horizontal bar supported by three springs.
- There is a top spring exerting a downward force \( F_s \) on the bar.
- Two lower springs are located on the left and right sides of the bar, exerting upward forces \( F_1 \) and \( F_2 \) respectively.
- The left spring applies a force \( F_1 \) of 6.10 N.
- The right spring applies a force \( F_2 \) of 9.60 N.
- The horizontal distance between the point where \( F_s \) acts and the left end of the bar is \( x \).
- The total length of the bar is \( \ell = 1.30 \, \text{m} \).

**Note:**
- Ensure the forces and positions result in rotational and translational equilibrium of the bar.
