Q1. What is the working principle of a four-stroke engine?
Ans. 
A four-stroke engine operates through four distinct strokes: intake, compression, power, and exhaust, converting fuel into mechanical energy.
• Intake Stroke: The engine draws in a mixture of air and fuel as the piston moves down, creating a vacuum.

• Compression Stroke: The piston moves up, compressing the air-fuel mixture, which increases its temperature and pressure.

• Power Stroke: A spark ignites the compressed mixture, ca...read more

Q2. What is the difference between stress and strain?
Ans. 
Stress is the internal force per unit area in materials, while strain is the deformation resulting from that stress.
• Definition: Stress is defined as force per unit area (σ = F/A), while strain is the measure of deformation (ε = ΔL/L).

• Units: Stress is measured in Pascals (Pa) or psi, whereas strain is a dimensionless quantity (no units).

• Types of Stress: There are different types of stress, such as tensile, compressive, ...read more

Q3. What is the second law of thermodynamics?
Ans. 
The second law of thermodynamics states that entropy in an isolated system always increases over time, indicating energy dispersal.
• Entropy Increase: In any energy transfer or transformation, the total entropy of a closed system can never decrease, leading to energy becoming less useful.

• Heat Transfer: Heat naturally flows from hot objects to cold ones, not the other way around, exemplified by a hot cup of coffee cooling...read more

Q4. What is the difference between heat and work?
Ans. 
Heat is energy transfer due to temperature difference, while work is energy transfer due to force acting over a distance.
• Definition: Heat is the transfer of thermal energy between systems, while work is the energy transfer resulting from a force acting through a distance.

• Direction: Heat flows from a hotter object to a cooler one, whereas work can be done in any direction depending on the applied force.

• Units: Both heat ...read more

Q5. What is pressure, and how is it measured?
Ans. 
Pressure is the force applied per unit area, commonly measured in pascals, atmospheres, or psi.
• Definition: Pressure is defined as the force exerted per unit area on a surface.

• Units of Measurement: Common units include pascals (Pa), atmospheres (atm), and pounds per square inch (psi).

• Measurement Instruments: Pressure is measured using devices like manometers, barometers, and pressure gauges.

• Example: Atmospheric pressure...read more
