Is there any one to give me UPSC Solved question papers of Mechanical Engineering???

Hello there , Yes we can surely provide you some papers of Mechanical Engineering of UPSC and also Solve all your other queries !!!!!!!!!!

Now as per your request here are some papers of Mechanical Engineering of UPSC and also Solve all your other queries :

For your Ease Here is a Glance at it :

Section 'A'

1.

(a) The critical buckling load of a cast iron hollow
cylindrical column 3 m in length when hinged
at both the ends is equal to P kN. When the
column is fixed at both the ends, its critical
load increases to (P + 300) kN. If the ratio
of external diameter to internal diameter is
1.25 and E = 100 GPa,

determine the external diameter of the column.

(b) A stuntman drives a motorcycle around a
circular vertical wall 30 m in diameter. The
coefficient of friction between the tyre and
wall is 0-6. Determine the minimum speed that
will prevent sliding down the wall.

Determine the angle also by which the motorcycle is
inclined to the horizontal.

(c) A hypoeutectoid plain c-steel is heated to
1540°C and then cooled slowly to 725°C.
What is the percentage of ferrite and austenite
in steel after the process ?

Mark the process on Iron-carbon diagram.

(d) An 1-beam with the following dimensions is
subjected to a shearing force of 20 kN.
Flange : breadth = 50 nun, thickness = 5.5 mm
Web : depth = 109 mm, thickness = 3.5 mm
Area of cross-section = 9.4 x 104mm2
M.I. = Ixx= 220 x 104mm4.

Calculate the value of the transverse shear stress at the neutral axis x-x and at the top of the web.
