MECHANICAL ENGINEERING INTERVIEW QUESTIONS
1.)How does iron ore turn into steel?
Ans:-To make Steel, Iron Ore is refined into iron and all the carbon is burned away using very high heat (Bessemer). A percentage of Carbon (and other trace elements) are added back to make
steel.

2.)What is knurling?
Ans:-Knurling is a machining process normally carried our on a centre lathe. The act of Knurling creates a raised crisscross pattern on a smooth round bar that could be used as a handle or
something that requires extra grip.

3.)What is extrued aluminum?
Ans:-Extrusion is the process where a metal or a metal bar is pulled through a mandrel to elongate it and/or give it a final shape.
Extruded Aluminum is a common form of making small aluminum wire, bars or beams and many varieties of small nonstructural, decorative pieces.

4.) What is a Newtonian fluid?
Ans:-A Newtonian fluid possesses a linear stress strain relationship curve and it passes through the origin. The fluid properties of a Newtonian fluid do not change when any force acts upon it.
