For example: In Thin cylinder topic following formulae are there:
1) Hoop Stress = Pd/2t
2) Longitudinal Stress= Pd/4t
3) Shear stress= Pd/8t
All the questions in paper 2 will be in Objective Multiple choice type only. Solving old GATE, IES, UPSC papers will help you in scoring decent marks. Following are some example questions:
1) The maximum value of Poissions ratio is -----
1) 1
2) 0
3) 0.2
4) 0.7
Answer: 1
2) The critical depth in rectangular channel is given by the relation ------
1) QT/gA=1
2) QT2 / gA2=1
3) QT3/ gA2=1
4) Q2T/ gA3=1
Answer: 2
Paper - 3 Preparation and Model Questions:
In Paper 3, about 40 percent questions will be asked on problems and 60 percent on theory. But in Paper -2, 70 percent of the questions will be from problems and remaining 30 percent will be on theory topics.
