Q1. What is diode? Why use in circuit
Ans. 
A diode is a semiconductor device that allows current to flow in one direction only. It is used in circuits to control the direction of current flow and to rectify AC to DC.
• Diodes are used to protect circuits from reverse polarity, preventing damage to sensitive components.

• They are used in rectifier circuits to convert AC voltage to DC voltage, such as in power supplies.

• Diodes are also used in signal processing circuit...read more

Q2. Types of Tolerances and explanation
Ans. 
Types of tolerances include bilateral, unilateral, limit, and fit tolerances.
• Bilateral tolerance: Allows for variation in both directions from the nominal dimension.

• Unilateral tolerance: Allows for variation in only one direction from the nominal dimension.

• Limit tolerance: Specifies the maximum and minimum acceptable limits for a dimension.

• Fit tolerance: Determines the acceptable range of tightness or looseness between

Q2. What is Hookes law
Ans. 
Hooke's law states that the force needed to extend or compress a spring by a certain distance is proportional to that distance.
• Describes the relationship between the force applied to a spring and the resulting displacement

• Mathematically represented as F = kx, where F is the force, k is the spring constant, and x is the displacement

• Used in mechanical engineering for designing springs, shock absorbers, and other elastic

Q1. Define stress and strain
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is the force applied per unit area on a material.

• Strain is the measure of deformation or change in shape of a material.

• Stress and strain are related by the material's modulus of elasticity.

• Stress is typically measured in units like Pascals or pounds per square inch.

• Strain is a dimensionless quantity representi
