Add your answer
Q2. How Diesel engine works
Ans. 
Diesel engine works by compressing air in the cylinder, injecting fuel, and igniting the mixture.
• Air is compressed in the cylinder by the piston

• Fuel is injected into the cylinder at high pressure

• The heat generated by the compressed air ignites the fuel

• The expanding gases push the piston down, creating power

• Diesel engines are more efficient than gasoline engines

Q1. How do you calculate the transmission energy loss in the vehicle?
Ans. 
Transmission energy loss in a vehicle can be calculated by considering factors like friction, heat generation, and mechanical inefficiencies.
• Calculate energy loss due to friction between moving parts

• Consider heat generation from components like the transmission fluid

• Account for mechanical inefficiencies in the transmission system

• Total the energy losses to get an overall estimate

Q2. Conscrete strength in 7 days and 28 days
Ans. 
Concrete strength increases significantly from 7 days to 28 days.
• Concrete strength is measured in terms of compressive strength.

• At 7 days, concrete typically reaches about 70-80% of its 28-day strength.

• Factors like cement type, water-cement ratio, curing conditions, and aggregate properties affect the strength development.

• Higher strength concrete is often required for structural applications.

• Testing concrete strength a...read more

Q4. Development length in compression member
Ans. 
Development length in compression member is the length of reinforcement required to transfer the stress from the steel to the concrete.
• Development length is determined by factors such as the strength of the concrete, the diameter of the reinforcement, and the bond strength between the steel and concrete.

• It is important to ensure that the development length is sufficient to prevent premature failure or slippage of the r...read more

Q5. Find cutting length oc a rectangular stirrups , numerical
Ans. 
The cutting length of a rectangular stirrup is calculated based on the dimensions of the stirrup and the bending requirements.
• The cutting length is determined by adding the lengths of all sides of the stirrup and multiplying by the number of bends.

• For example, if the stirrup has sides measuring 10 cm, 15 cm, and 10 cm, and it requires 2 bends, the cutting length would be (10 + 15 + 10) * 2 = 70 cm.

• The cutting length is...read more

Q1. Difference between flexible and rigid pavement? different layers of highway? superelevation and camber values for different types of roads? types of field test in highways?
Ans. 
Explanation of pavement types, highway layers, superelevation and camber values, and field tests in highways.
• Flexible pavement is made of bituminous materials and can bend under traffic loads, while rigid pavement is made of concrete and cannot bend.

• Highway layers include subgrade, subbase, base, and surface layers.

• Superelevation is the banking of a road on a curve, while camber is the slope of the road surface.

• Superel...read more
