FAQs on Stress & Strain - 1 Video Lecture - Physics for JAMB
| 1. What is stress and strain? |  |
Ans. Stress is the force per unit area applied to an object, while strain is the resulting deformation or change in shape of the object. Stress and strain are related to each other through the material's mechanical properties and can be used to analyze the behavior of materials under external forces.
| 2. What are the types of stress? | |
Ans. There are three main types of stress:
1. Tensile stress: This occurs when a material is being pulled or stretched, causing it to elongate.
2. Compressive stress: This occurs when a material is being compressed or squeezed, causing it to shorten.
3. Shear stress: This occurs when a material is being subjected to parallel forces in opposite directions, causing it to deform by sliding or twisting.
| 3. How is stress calculated? | |
Ans. Stress is calculated by dividing the applied force by the cross-sectional area of the object. The formula for stress is stress = force / area. The resulting stress is typically expressed in units of pressure, such as pascals (Pa) or pounds per square inch (psi).
| 4. How is strain measured? | |
Ans. Strain is typically measured as the ratio of the change in length or deformation of an object to its original length. It is represented by the symbol ε (epsilon) and is calculated using the formula: strain = change in length / original length. Strain is a dimensionless quantity and is usually expressed as a decimal or a percentage.
| 5. What is the relationship between stress and strain? | |
Ans. The relationship between stress and strain is defined by the material's elastic properties, specifically its Young's modulus or modulus of elasticity. Young's modulus is a measure of how much a material deforms under stress. It is given by the equation: stress = Young's modulus × strain. This relationship allows us to determine the behavior of a material when subjected to external forces.
