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

Q1. STRESS STRAIN DIAGRAM
Ans. 
A stress-strain diagram shows the relationship between stress and strain in a material.
• It typically consists of a linear elastic region, a yield point, and a plastic deformation region.

• The slope of the linear region is the material's Young's Modulus.

• The yield point is where the material begins to deform plastically.

• The ultimate tensile strength is the maximum stress the material can withstand.

• The breaking point is wher...read more

Q2. EXPLAIN SN CURVE
Ans. 
SN curve is a graphical representation of fatigue data showing the relationship between stress and number of cycles to failure.
• SN curve helps in understanding the fatigue behavior of materials under cyclic loading.

• It shows the stress level at which a material will fail after a certain number of cycles.

• The curve typically consists of a high cycle fatigue region and a low cycle fatigue region.

• Example: Steel SN curve show...read more

There was a panel of 8 member .They gave us case study of one paragraph in which we have to speak for 15 min and remaining 15 min for conclusion.

Round 1 consisted of an aptitude test comprising three subjects: 1. Technical subject test, 2. Verbal and non-verbal reasoning, and 3. Behavioral aptitude. The format of the aptitude test was quite unique; it did not feature a simple one-click answer method. Instead, it offered an interactive approach to answering questions, which participants should familiarize themselves with prior to the actual test.

Q1. Write CNC coding for a component
Ans. 
CNC coding is used to program machines to create precise components.
• Use G-code and M-code to control the machine movements and functions

• Specify tool paths, speeds, feeds, and other parameters

• Example: G01 X10 Y5 Z2 F100

Q2. Valve port diagram for 4 stroke engine
Ans. 
Valve port diagram for a 4-stroke engine shows the intake and exhaust valves in relation to the piston movement.
• Intake valve opens to allow air/fuel mixture into the cylinder during the intake stroke

• Exhaust valve opens to release exhaust gases during the exhaust stroke

• Valve overlap occurs when both intake and exhaust valves are partially open at the same time

• Diagram typically shows the position of valves in relation to...read more
