A long column such as the one depicted below loaded in compression initially along its axis has a tendency to rotate. Associated with that rotation the load P imparts tipping moments that are resisted by the springs. In the configuration below the springs are connected to the rod with a frictionless slider and remain perpendicular to the rod. The pivot at O is also frictionless, and the masses of the structure are negligible. P k (spring) Assume that the springs are at their happy (natural/unstretched) length when 0 = 0. (a) Let the spring constant k, the lengths b, L, and d be given parameters in the problem. Find the load load P as a function of the rotation angle 9 such that the system is in static equilibrium.

**Diagram Explanation:**
The diagram shows a column under load \( P \). Key components and labels in the diagram include:
- The column is labeled with length \( L \).
- The load \( P \) acts vertically downward at the top left end of the column.
- The column is anchored at point \( O \), which acts as a frictionless pivot.
- Two springs with spring constant \( k \) are attached perpendicularly to the rod at point \( O \). The springs are positioned such that they maintain their natural (unstretched) length when the rotation angle \( \theta = 0 \).
- Distance from the pivot \( O \) to where springs attach to the ground is labeled as \( b \).
- A distance \( d \) is shown from where \( P \) is applied to the top of the column, measured perpendicularly.
**Assumptions:**
Assume that the springs are at their happy (natural/unstretched) length when \(\theta = 0\).
**Problem Statement:**
(a) Let the spring constant \( k \), the lengths \( b, L \), and \( d \) be given parameters in the problem. Find the load \( P \) as a function of the rotation angle \(\theta\) such that the system is in static equilibrium.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fee20147b-f1dd-4746-b03b-f8f585cfa325%2Ff566df62-175c-4893-b99b-e230fb085006%2Fk40vz7n_processed.png&w=3840&q=75)
