Q1. 1.What is theories of failure?
Ans. 
Theories of failure are mathematical models used to predict the failure of materials under different loading conditions.
• Theories of failure help engineers design structures that can withstand different types of loads.

• Some common theories of failure include maximum shear stress theory, maximum normal stress theory, and maximum strain energy theory.

• These theories are based on different assumptions about the behavior of m...read more

Q2. 2. What is the working principle of diesel cycle?
Ans. 
Diesel cycle is a thermodynamic cycle used in diesel engines to convert heat into work.
• Air is compressed in the cylinder, causing its temperature to rise.

• Fuel is injected into the cylinder, igniting due to the high temperature.

• The expanding gases push the piston, converting heat into mechanical energy.

• Exhaust gases are expelled from the cylinder.

• Diesel cycle is more efficient than Otto cycle used in gasoline engines.

Q2. What is young's modulus and ultimate tensile strength? And what are their SI units?
Ans. 
Young's modulus is a measure of stiffness of a material while ultimate tensile strength is the maximum stress a material can withstand.
• Young's modulus is the ratio of stress to strain in a material under tension or compression.

• Ultimate tensile strength is the maximum stress a material can withstand before breaking.

• Young's modulus is measured in pascals (Pa) while ultimate tensile strength is measured in newtons per squ

Q4. What is meant by enthalpy?
Ans. 
Enthalpy is the sum of internal energy and the product of pressure and volume.
• Enthalpy is a thermodynamic property of a system.

• It is represented by the symbol 'H'.

• It is defined as the sum of internal energy and the product of pressure and volume.

• Enthalpy change is the difference between the enthalpies of the products and reactants in a chemical reaction.

• Enthalpy is used in various fields including chemistry, physics, a
