Q1. Diffrent types of gears
Ans. 
Different types of gears include spur gears, helical gears, bevel gears, worm gears, and rack and pinion gears.
• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother operation but produce axial thrust.

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

• Worm gears have a screw-like appearance and are used for high reduction ratios.

Q2. What's critical velocity
Ans. 
Critical velocity is the minimum velocity needed for an object to overcome a specific force or resistance.
• Critical velocity varies depending on the force or resistance being overcome

• It is often used in fluid dynamics to determine the speed at which a fluid flow transitions from laminar to turbulent

• For example, in aerodynamics, critical velocity is the speed at which an aircraft's lift equals its weight, allowing it to

Q3. What's pitting in metal structures
Ans. 
Pitting in metal structures refers to localized corrosion that creates small holes or cavities on the surface.
• Pitting corrosion occurs when a small area on the metal surface becomes anodic, while the surrounding area becomes cathodic.

• It is often caused by exposure to corrosive environments, such as saltwater or acidic solutions.

• Pitting can lead to structural weakness and eventual failure if not addressed.

Q1. Grade of cement
Ans. 
Grade of cement refers to the strength of the cement based on the compressive strength it can achieve after 28 days of curing.
• Cement grades are classified as 33, 43, and 53 based on their compressive strength in MPa.

• Grade 33 cement has a compressive strength of 33 MPa, grade 43 has 43 MPa, and grade 53 has 53 MPa.

• Higher grade cement is used for construction projects that require high strength like bridges and high-rise

Q2. Which ingredient provide strength and hardnes in cement
Ans. 
The ingredient that provides strength and hardness in cement is calcium silicate.
• Calcium silicate reacts with water to form calcium silicate hydrate, which contributes to the strength and hardness of cement

• Other ingredients like alumina and iron oxide also contribute to the strength of cement

• The ratio of these ingredients in cement mix determines the final strength and hardness of the cement
