Simple mechanical engineering

Q1. Stress strain curve in detail
Ans. 
Stress strain curve shows the relationship between stress and strain in a material under tension.
• Stress strain curve is a graphical representation of the relationship between stress (force per unit area) and strain (deformation) in a material.

• It typically consists of a linear elastic region, a yield point, a plastic deformation region, and ultimately failure.

• The slope of the curve in the elastic region is the material'...read more

Q2. Laws of thermodynamics
Ans. 
The laws of thermodynamics are fundamental principles that govern energy and its transformations in the universe.
• First Law: Energy cannot be created or destroyed, only transferred or converted.

• Second Law: The entropy of a closed system will always increase over time.

• Third Law: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• Examples: A car engine converting fuel into motion (...read more
