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. How stress is related to strain
Ans. 
Stress and strain are related as stress is the force applied per unit area, while strain is the deformation caused by stress.
• Stress is the force applied per unit area, while strain is the deformation caused by stress.

• Stress is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa).

• Strain is measured as the change in length or shape of a material due to stress, and is typically ex...read more

Q2. What is distillation?
Ans. 
Distillation is a process of separating components of a mixture based on their boiling points.
• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants.

• Examples include the distillation of crude oil to ...read more

Q5. What is heat exchanger and it's working?
Ans. 
A heat exchanger is a device used to transfer heat between two or more fluids.
• Heat exchangers are used in various industries such as chemical, power, and HVAC.

• They work by allowing two fluids to flow through separate channels, with heat transferring from one fluid to the other.

• Common types of heat exchangers include shell and tube, plate and frame, and finned tube.

• Heat exchangers can be used for heating, cooling, or bo...read more

Q2. What are the values of Compressive & Tensile Shear Stress on a Singly Reinforced Beam in LSM method?
Ans. 
Compressive shear stress is zero while tensile shear stress is equal to the shear force divided by the cross-sectional area of the beam.
• Compressive shear stress is zero in a singly reinforced beam according to the Limit State Method (LSM).

• Tensile shear stress is calculated by dividing the shear force by the cross-sectional area of the beam.

• For example, if the shear force acting on the beam is 10 kN and the cross-sectio...read more

Q1. Should we continue concreting of foundation the next day, if there is one day of continuous rainfall?
Ans. 
No, it is not advisable to continue concreting of foundation the next day after one day of continuous rainfall.
• Continuous rainfall can saturate the soil, making it unstable for concreting.

• Rainwater can mix with the concrete, affecting its strength and durability.

• The presence of water can lead to the formation of voids and cracks in the foundation.

• It is important to ensure that the foundation is dry and stable before pr...read more
