### Transcription of Shaft Mechanics Diagram #### (a) Overview of Shaft This section shows a diagram of a shaft with several key features marked: - **Thrust Bearing:** Located at one end of the shaft. - **P (Axial Load):** An arrow pointing downward in the center of the shaft, indicating the direction of the axial load applied to the shaft. - **Length L:** The horizontal extent of the shaft is marked as "L". - **T (Torque):** An arrow in a circle at the end of the shaft, representing the torque applied. #### (b) Zoom-in View of a Solid Particle This section provides a detailed view of a solid particle at the bottom middle of the shaft: - **τ (Shear Stress):** Indicated by arrows directed along the top and bottom of the particle, suggesting the force applied parallel to the surface. - **σₓ (Normal Stress):** Arrows pointing outward from the left and right sides of the particle, indicating the normal stress acting on these surfaces. #### (c) Zoom-in “Top” View of the Solid Particle This section offers a top view of the solid particle from section (b): - **σₓ (Normal Stress):** Demonstrated by arrows pointing outward from the left and right sides of the particle's top view. - **τₓₓ (In-Plane Shear Stress):** Arrows positioned diagonally at the corners of the particle. - **σᵧ = 0:** Indicating that the normal stress in the vertical direction is zero. - **τᵧ = 0:** Indicating that there is no shear stress in the vertical direction. This diagram is an educational representation of the forces and stresses acting on a shaft, useful for understanding mechanical properties and stress analysis in engineering contexts.

**Problem 1** Compute all the stresses mentioned above at the solid particle shown in Fig. 1(c). Use the following formula and values for computing stresses (\(\tau\) and \(\sigma\)). Then, draw the Mohr's circle for this solid. \[ \tau = \frac{Tr}{J}, \quad \sigma = \frac{Mr}{I}, \quad J = \frac{\pi r^4}{2}, \quad I = \frac{\pi r^4}{4} \] \[ P = 1000 \, \text{N}, \quad L = 1 \, \text{m}, \quad T = 400 \, \text{Nm}, \quad r = 0.05 \, \text{m} \] **Explanation of Diagrams/Graphs:** - No specific diagrams or graphs are provided in the text. However, it references drawing a Mohr's circle, which is a graphical representation used to determine the principal stresses, maximum shear stresses, and the orientation of these stresses within a material. To construct Mohr's circle, you typically plot normal stress (\(\sigma\)) on the x-axis and shear stress (\(\tau\)) on the y-axis.
