Question

Accepted Answer

Thermodynamics, stress and strain determination, manufacturing processes, CAD software proficiency, IC engine operation, Otto cycle explanation

Basic principles of thermodynamics involve energy transfer and conversion, entropy, and the laws of thermodynamics
Stress in a material is determined by dividing the applied force by the cross-sectional area, while strain is the ratio of the change in length to the original length
Types of manufacturing processes include casting, machining, welding, and additive manufacturing
Proficiency in CAD software like AutoCAD, SolidWorks, or CATIA is essential for designing mechanical components
The 4 steps of an IC engine are intake, compression, power, and exhaust strokes
IC engines are used for powering vehicles, generators, and various machinery due to their efficiency and power output
The Otto cycle is a theoretical thermodynamic cycle for spark-ignition engines, involving four processes: isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection

Accepted Answer

Thermodynamic is a branch of physics that studies of relationship between heat work, temperature and energy. 
Stress and strain is a material are used to Analyze mechanical behaviour under load. 
There are four types of Ic engine. 
Intake, Compression ,Combustion,
 Exhaust
