Question
100%

I need help with this problem. If possible can it be done on paper because I want to be able to follow through the steps!!

**Problem Description:**

*The 30-N force causes the bar to tip \( \theta = 13^\circ \) when the force is applied. Originally the bar is horizontal and the springs are unstretched.* 
[Visual Aid: Figure 1]

**Objective:**

Determine the stiffness \( k \) of each spring. Neglect the weight of the bar.

**Instructions:**

Express your answer to three significant figures and include the appropriate units.

**Input Box:**
- Enter the value of \( k \) in \(\frac{\text{N}}{\text{m}}\).

**User Feedback:**
- Submission Status: Incorrect; Try Again; 5 attempts remaining.

**Diagram Description:**

- **Figure 1:** 
  - A horizontal bar is supported by two springs on each end.
  - The left spring is positioned 1 meter from the point of force application.
  - The right spring is positioned 3 meters from the point where a 30 N force is applied.
  
**Task:**

Calculate the spring constant (\( k \)) needed for the system to maintain equilibrium when displaced by a 30 N force causing a 13° tilt.
