Q1. Explain about stress strain curve
Ans. 
The stress-strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• The curve typically consists of several distinct regions: elastic deformation, yield point, plastic deformation, and ultimate failure.

• In the elastic region, the material deforms elastically and returns to its original shape when the stress is removed.

• The yield point is where the material transi...read more

Q2. What are gears and types of gears
Ans. 
Gears are mechanical components used to transmit motion and power between rotating shafts. There are various types of gears including spur, helical, bevel, and worm gears.
• Gears are toothed mechanical components that mesh together to transmit motion and power.

• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have cone-shaped...read more

Q4. What do you mean by tolerance.
Ans. 
Tolerance refers to the allowable deviation from a specified dimension or value in engineering.
• Tolerance is important in manufacturing to ensure that parts fit together properly.

• It is typically specified as a range, such as +/- 0.1mm.

• Tolerance can be applied to dimensions, angles, surface finishes, and other characteristics.

• For example, a hole may have a tolerance of +/- 0.05mm to allow for variations in the drilling p
