Q1. Thermodynamics 3 laws
Ans. 
The three laws of thermodynamics describe the relationships between energy, heat, and work in a system.
• First Law: Energy cannot be created or destroyed, only transferred or converted.

• Second Law: Heat naturally flows from hot to cold objects, and not the other way around.

• Third Law: As temperature approaches absolute zero, the entropy of a perfect crystal approaches zero.

Q2. What is Carnot cycle and efficiency?
Ans. 
Carnot cycle is a theoretical thermodynamic cycle that operates between two heat reservoirs to achieve maximum efficiency.
• Carnot cycle consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression.

• The efficiency of Carnot cycle is given by the formula: Efficiency = 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperatu...read more

Q3. Newton's second law of motions?
Ans. 
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
• F = ma, where F is the net force, m is the mass of the object, and a is the acceleration

• The direction of the acceleration is the same as the direction of the net force

• The SI unit of force is Newton (N)

• Example: A car accelerates faster when a greater force

Q4. Bernoulli theorem.
Ans. 
Bernoulli's theorem states that in a steady flow of fluid, the sum of pressure energy, kinetic energy, and potential energy per unit volume remains constant.
• Describes the relationship between pressure, velocity, and elevation in a fluid flow

• Used to analyze fluid flow in pipes, pumps, and other hydraulic systems

• Can be applied to calculate pressure drop in a pipe or the lift of a pump

Q5. Define Pascal's law
Ans. 
Pascal's law states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.
• Pressure applied to a confined fluid is transmitted equally in all directions

• The pressure at any point in a fluid is the same in all directions

• Used in hydraulic systems to generate force or motion

• Example: Hydraulic car lift operates based on Pascal's law

Q1. What is the least count of Micrometer
Ans. 
The least count of a micrometer is the smallest measurement that can be accurately read on the micrometer scale.
• The least count is determined by the number of divisions on the micrometer scale and the pitch of the screw.

• It is usually expressed in micrometers or millimeters.

• For example, if a micrometer has 50 divisions on the scale and the pitch of the screw is 0.5 mm, then the least count would be 0.01 mm (0.5 mm / 50

Q2. What is type of defect in bearing?
Ans. 
The types of defects in bearings include wear, corrosion, pitting, cracking, and misalignment.
• Wear: Occurs due to friction and can lead to loss of material and increased clearance.

• Corrosion: Caused by chemical reactions, leading to surface degradation and reduced performance.

• Pitting: Localized surface damage caused by fatigue or contaminants, resulting in roughness and reduced load-carrying capacity.

• Cracking: Can occur...read more
