**Problem Statement for Educational Website**---**Topic: Elastic Energy in Rotational Systems****Scenario:**The given data corresponds to questions 12, 13, and 14. We have an 8-kg slender bar AB that is initially horizontal and at rest. A spring is attached to the bar. The spring has an unstretched length (\(s_0\)) of 1 meter and a spring constant (\(k\)) of 15 N/m. The entire length of the bar AB (\(l\)) is 1.5 meters.**Objective:**Determine the elastic energy stored in the spring once the bar has rotated by an angle \(\theta = 45^\circ\) clockwise from its initial position. The answer should be rounded to two decimal places.**Diagram Description:**A diagram illustrates the setup:- The bar \(AB\) is extended horizontally with point \(A\) attached to a fixed wall.- Point \(B\) is connected to a spring, which is anchored vertically above point \(B\).- The spring is shown in a vertical orientation, with its natural length labeled as \(s_0\).- The spring is extended or compressed as the bar rotates, indicated by a change in its length in the diagram.**Problem Solving Approach:**To find the elastic energy, use the formula for elastic potential energy in a spring:\[ Ee = \frac{1}{2} k (s - s_0)^2 \]Where \(s\) is the new length of the spring after rotation. Calculate \(s\) using the components of the motion as the bar rotates \(45^\circ\).---This explanation is structured to guide students through understanding the problem setup, objectives, and steps necessary to solve for the elastic energy within a physical rotational system.

Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.
