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 Hookes law is used in Suspension System?
Ans. 
Hooke's law is used in suspension systems to determine the spring rate and design components for optimal performance.
• Hooke's law states that the force needed to extend or compress a spring by a certain distance is proportional to that distance.

• In suspension systems, Hookes law is used to calculate the spring rate, which determines how stiff or soft the suspension will be.

• By applying Hookes law, engineers can design sus...read more

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
