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. 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
