3. Try to strike out options before coming to concluding answer.
4. Many a times questions are tricky and the clue is given right in the question iteslf.

1. A body submerged in static fluid will undergo
(A) Longitudinal strain 
(B) Lateral strain
(C) Volumetric strain
(D) Zero Strain

Ans: C: The pressure inside static fluid is same in all directions hence the body will undergo Volumetric strain


2. Which of these manufacturing process is best suitable for cutting thin sheets
(A) Milling 
(B) Broaching
(C) Gas cutting
(D) Chemical machining

Ans: D: Chemical machining is best suited for cutting thin sheets as all other processes will cause warping of the sheet.
