### (a) Types of Destructive Testing Methods
Destructive Testing (DT) involves the physical destruction of a test specimen to determine its fundamental mechanical properties and behavior under various loads. These tests provide quantitative data crucial for material selection, design, and quality control. The primary methods used are:
1. **Tensile Testing**
* **Objective**: To determine the ultimate tensile strength (UTS), yield strength, ductility (% elongation and % reduction in area), and modulus of elasticity of a material.
