Q1. Types of gears & explain brifly?
Ans. 
Types of gears include spur, helical, bevel, worm, rack and pinion, and planetary gears.
• Spur gears have straight teeth and are the most common type.

• Helical gears have angled teeth for smoother operation.

• Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

• Worm gears have a screw-like appearance and provide high gear reduction ratios.

• Rack and pinion gears convert rotational motion into lin...read more

Q2. Thermodynamics laws?
Ans. 
Thermodynamics laws govern energy transfer and transformation in physical systems.
• First Law of Thermodynamics: Energy cannot be created or destroyed, only transferred or converted.

• Second Law of Thermodynamics: Entropy in a closed system will always increase over time.

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

• Examples: A car engine converting...read more

Q3. Stress & strain diagram?
Ans. 
Stress-strain diagram shows the relationship between stress applied to a material and the resulting strain.
• It is a graphical representation of how a material deforms under stress.

• The diagram typically shows a linear elastic region, a yield point, plastic deformation, and ultimate failure.

• The slope of the linear region is the material's Young's Modulus.

• The area under the stress-strain curve represents the material's tou...read more

Q4. What is knocking?
Ans. 
Knocking is the unwanted sound produced in an internal combustion engine due to improper combustion of the air-fuel mixture.
• Knocking occurs when the air-fuel mixture ignites spontaneously before the spark plug fires.

• It can lead to engine damage if not addressed promptly.

• Knocking can be caused by factors such as low octane fuel, incorrect ignition timing, or carbon deposits in the combustion chamber.

Q5. Carbon contains of steel?
Ans. 
Carbon is a key element in steel, affecting its strength, hardness, and other properties.
• Carbon content in steel typically ranges from 0.2% to 2.1%.

• Higher carbon content results in harder and stronger steel.

• Low carbon steel (0.05-0.30% carbon) is more ductile and easily weldable.

• High carbon steel (0.60-2.0% carbon) is more brittle and used for cutting tools.

• Carbon steel is widely used in construction, automotive, and m...read more

Q1. What is charaterstic strength
Ans. 
Characteristic strength is the maximum stress that a material can withstand before failure.
• Characteristic strength is a measure of the maximum stress a material can handle.

• It is often used in engineering to determine the safety factor of a material.

• For example, the characteristic strength of steel is typically around 400 MPa.
