Q1. Mechanical properties of material
Ans. 
Mechanical properties of materials refer to their ability to withstand applied forces without failure.
• Mechanical properties include strength, hardness, toughness, ductility, and elasticity.

• Strength is the ability of a material to withstand an applied force without failure.

• Hardness is the resistance of a material to deformation or scratching.

• Toughness is the ability of a material to absorb energy and plastically deform ...read more

Q2. What is difference between stress and strain.
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is a measure of the internal resistance of a material to deformation under an applied force.

• Strain is the measure of the deformation or displacement of material in response to stress.

• Stress is typically measured in units of force per unit area (such as N/m^2 or Pa), while strain is dimensionless.

• Stress can cau...read more

Q1. Tell us about ohm's law
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given constant resistance.
• Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It is named after German physicist Georg Simon Ohm.

• It is commonly used in electrical engineering to calculate the relationship between voltage, current, and resistance.

• Ohm's law is ...read more

Q2. How many types of transformer
Ans. 
There are mainly two types of transformers: Step-up transformers and Step-down transformers.
• Step-up transformers increase the voltage from primary to secondary winding.

• Step-down transformers decrease the voltage from primary to secondary winding.

• Examples include power transformers, distribution transformers, and instrument transformers.
