Question

A shaft, lever, and handle, welded together, with a combined mass of 20 kg acting at point G, supported by a thin link, CD, and two journal bearings, A and B. (Draw a single FBD for the combined rigid body shaft + lever + handle.)

### Problem Statement: **b.** A shaft, lever, and handle, welded together, with a combined mass of 20 kg acting at point \( G \), supported by a thin link, \( CD \), and two journal bearings, \( A \) and \( B \). Draw a single FBD for the combined rigid body shaft + lever + handle. ### Diagram Explanation: The diagram illustrates a mechanical system composed of a shaft, lever, and handle that are welded together. Key features and dimensions include: - **Journal Bearings:** - **A and B:** These are the supports for the shaft. The shaft is horizontal and is mounted on bearings \( A \) and \( B \). - **Link \( CD \):** - A thin link connected from point \( C \) on the shaft to point \( D \). It is an angled support for the system. - **Length Information for Link CD:** - \( CD \) is 15 inches long. - The vertical distance from \( D \) to the shaft's line is 10 inches. - The horizontal distance from \( C \) to \( D \) perpendicular to \( AB \) is noted as 2 inches. - **Dimensions Along the Shaft:** - The distance from \( A \) to \( B \) is 12 inches. - Point \( G \) is located 5 inches from bearing \( A \). - Point \( C \) is located 4 inches from the left end of the shaft (bearing \( A \)). - The overhang beyond bearing \( B \) is not dimensioned but is suggested visually. - **Moments and Forces:** - A moment of 50 lb-in is applied at a section marked by a handle near the left of the diagram. - The combined weight \( w = mg \) acts downward at point \( G \). - **Coordinate System:** - The shaft's orientation is aligned with the \( z \)-axis, while the vertically downward direction and the extension of link \( CD \) define upward and angled dimensions. An \( xy \) plane is indicated with \( x \) running horizontally and \( y \) vertically. This information can be used to draw a free-body diagram (FBD) which helps in analyzing the forces and moments acting on the system.
