## Analysis of Stresses in a Square Member### Problem StatementA square member (400 mm x 400 mm) sustains an internal shear force of 150 kN and an internal bending moment of 250 kN-m, as shown in the diagram. ### Diagram DescriptionThe diagram illustrates a 3D view of the square member. The coordinates are marked as x, y, and z. - A shear force of 150 kN is applied, depicted by an arrow pointing along the positive y-axis.- A bending moment of 250 kN-m is applied, shown by a curved arrow around the z-axis.- Point P is marked on the member, near one side of the square cross-section.### Questions and Answers(a) **What is the axis of bending?**- The bending is about the z-axis, as indicated by the curved arrow.(b) **What is the moment of inertia about the axis of bending?**- **Answer:** The moment of inertia is not provided directly. It would typically need to be calculated based on cross-sectional geometric properties.(c) **Compute the stress at Point P that results from the shear force.**- **Answer:** 1.05 MPa(d) **Compute the stress at Point P that results from the bending moment.**- **Answer:** 11.7 MPa(e) **Illustrate the combined state of stress at Point P on this stress cube.**- This would involve drawing the three-dimensional stress cube at Point P with the respective shear and normal stresses calculated in the previous steps. The stress cube is visually represented in the document as a 3D block aligned with the coordinate axes.This layout gives an overview of how to analyze structural members under combined loading conditions.

Given: A square cross section of 400mm × 400mm Shear force = 150KN Bending moment = 250KN-m Required: Axis of bending Moment of inertia about axis of bending Shear stress at Point P Note: As per bartleby guidelines, only 1st 3 parts need to be solved. For rest of the parts, please post them as a separate question and mention there to solve only those.
