### Problem StatementA crate is attached to a rotating crane with a rope as shown in the diagram. The rope has a length of 8 meters, and the length of the crane’s arm is unknown. The crane rotates around a vertical axis with a constant rotation rate of 0.3 rad/s. The rope is angled 15 degrees with the vertical. Determine the length of the crane’s arm.### Diagram Explanation- The diagram depicts a crane with a vertical arm and a horizontal arm, labeled with length \( L \).- A rope is attached to the end of the crane arm, holding a crate.- The rope makes an angle of 15 degrees with the vertical.- The length of the rope is 8 meters.- The rotation rate of the crane around the vertical axis is 0.3 rad/s.- The gravitational force \( g \) acts vertically downward.### Solution ApproachTo solve this problem, we need to consider the geometry of the setup and the forces involved due to the rotation of the crane. Using trigonometric relationships and the given rotational dynamics, we can find the length \( L \) of the crane's arm.
