Q2. What is elasticity and it's use in rubber
Ans. 
Elasticity is the ability of a material to return to its original shape after being stretched or compressed. It is important in rubber for its ability to absorb shock and provide flexibility.
• Rubber is a highly elastic material due to its long polymer chains that can stretch and return to their original shape.

• Elasticity in rubber is important for its use in tires, where it allows the tire to absorb shock and maintain co...read more

Q1. What is stress and strain?
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is the external force acting on an object, measured in units like Newtons per square meter (N/m^2) or Pascals (Pa).

• Strain is the measure of deformation or change in shape of a material due to stress, expressed as a ratio or percentage.

• Example: When you stretch a rubber band (apply stress), it elongates (strain

Q3. What is automobile, what is otto ,dual,diesels cycle difference
Ans. 
The question is about the basics of automobile engines and the differences between Otto, Dual, and Diesel cycles.
• Automobile is a vehicle powered by an engine that converts fuel into mechanical energy.

• Otto cycle is a four-stroke combustion cycle used in gasoline engines.

• Dual cycle is a modified version of the Otto cycle that includes a constant volume heat addition process.

• Diesel cycle is a four-stroke combustion cycle ...read more

Q4. What is coefficient of performance input/output
Ans. 
Coefficient of performance (COP) is the ratio of output heat to input work or energy.
• COP is used to measure the efficiency of a heat pump or refrigeration system.

• It is calculated by dividing the output heat by the input work or energy.

• A higher COP indicates a more efficient system.

• For example, a heat pump with a COP of 3 can produce three units of heat for every unit of energy input.

• COP can also be expressed in terms o...read more

Q5. How the otto cycle constants volume this process,
Ans. 
The Otto cycle is a constant volume process used in internal combustion engines.
• The Otto cycle consists of four processes: intake, compression, combustion, and exhaust.

• During the intake process, the fuel-air mixture is drawn into the cylinder.

• During the compression process, the mixture is compressed to a smaller volume, increasing its temperature and pressure.

• During the combustion process, the mixture is ignited, causi...read more

Q6. What is the Duel cycle principles -both constant volume, and pressure
Ans. 
Dual cycle principles involve both constant volume and pressure processes in an engine cycle.
• Dual cycle is a combination of Otto and Diesel cycles.

• It involves two constant volume and one constant pressure processes.

• The first constant volume process is isentropic compression.

• The constant pressure process is combustion.

• The second constant volume process is isentropic expansion.

• It is used in gas turbine engines and some i

Q8. Efficiency of carnot T1/T2-T1
Ans. 
Efficiency of Carnot cycle is given by T1/T2-T1
• Efficiency of Carnot cycle is the maximum possible efficiency of a heat engine

• It depends only on the temperatures of the hot and cold reservoirs

• Efficiency = 1 - (T1/T2)

• T1 is the temperature of the cold reservoir and T2 is the temperature of the hot reservoir
