Q1. What is the stress-strain curve for various materials?
Ans. 
The stress-strain curve illustrates how materials deform under stress, showing elastic and plastic behavior.
• Elastic Region: Material returns to original shape after stress is removed (e.g., rubber).

• Yield Point: The stress at which material begins to deform plastically (e.g., steel).

• Plastic Region: Permanent deformation occurs (e.g., clay).

• Ultimate Tensile Strength: Maximum stress material can withstand (e.g., aluminum)...read more

Q2. What is a bending moment diagram, and how is it constructed?
Ans. 
A bending moment diagram visually represents the bending moments along a beam, aiding in structural analysis.
• A bending moment diagram (BMD) shows how bending moments vary along the length of a beam.

• Constructed by calculating moments at various points due to applied loads.

• Positive moments typically indicate sagging, while negative moments indicate hogging.

• Example: For a simply supported beam with a central load, the BMD...read more
