Q1. What is the Vernier caliper least count?
Ans. 
The Vernier caliper least count is the smallest measurement that can be read on the caliper scale.
• The least count of a Vernier caliper is determined by the number of divisions on the main scale and the Vernier scale.

• It is calculated by dividing the smallest division on the main scale by the total number of divisions on the Vernier scale.

• For example, if the smallest division on the main scale is 0.1 mm and the total num...read more

Q2. What is stress and strain comparision?
Ans. 
Stress and strain are related concepts in materials science and engineering.
• Stress is the force applied to a material per unit area, causing deformation.

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

• Stress and strain are directly proportional within the elastic limit of a material.

• Stress is measured in units of force per unit area (such as N/m² or Pa).

• Strain is a dimensionless ...read more

Q5. Difference b/w 2stroke and 4 stroke comparison?
Ans. 
2-stroke engines have a power stroke every revolution, while 4-stroke engines have a power stroke every other revolution.
• 2-stroke engines have a simpler design and are lighter than 4-stroke engines.

• 2-stroke engines have a higher power-to-weight ratio than 4-stroke engines.

• 4-stroke engines are more fuel-efficient and have a longer lifespan than 2-stroke engines.

• 2-stroke engines are commonly used in small power tools and...read more
