Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

### Problem Details

At the instant shown, the angular velocity of rod \( DE \) is \( 11 \, \text{rad/s} \) clockwise, and the angular velocity of bar \( EF \) is \( 16 \, \text{rad/s} \) counterclockwise.

### Diagram Explanation

The diagram illustrates a mechanical linkage system with the following components:

- **Rod \( DE \):** Horizontal rod at the top, rotating at \( 11 \, \text{rad/s} \) clockwise.
- **Bar \( EF \):** Vertical bar on the right, measuring \( 15 \, \text{in.} \), rotating at \( 16 \, \text{rad/s} \) counterclockwise.
- **Bar \( AB \):** Diagonal bar forming a \( 45^\circ \) angle with the horizontal base \( A \).
- **Distance \( DE \):** \( 20 \, \text{in.} \)

### Objective

Determine the angular velocity of bar \( AB \).

### Solution

The angular velocity of bar \( AB \) is calculated to be:

\[
15.35 \, \text{rad/s} \, \circlearrowleft
\]

This information can be used in conjunction with kinematic equations and vector analysis to analyze the motion of the system and understand the relationship between different components' angular velocities.
