Re: UPSC Mechanical Engineering Paper II (Conventional Papers) Previous Years Questio

For you reference, here I am providing you Previous Years Question Paper of UPSC Mechanical Engineering Paper II (Conventional Papers)

1. (a) A balance mass of -value is placed diametrically opposite to the crank at crank radius r. “Hiat -is the expression for the unbalanced force along the line of stroke of a reciprocating engine for angular position 8 of'the crank with respect to the line of stroke ?
(b) (i) What is an isochronous governor ?
(ii) State the phenomenon of hunting in a spring controlled governor.
(c) (i) Explain brieﬂy vibration isolation. And transmissibility.
(ii) The natural frequency of a system put on'a -.. foundation is (on. The operating frequencyr
11 is o). What is the minimum value of x \beyond which the vibration isolation is possible or meaningful ?

(d) The Mohr’s circle for a plane stress is a circle of radius R with its origin at +2R on 0' axis. Sketch the Mohr’s circle and determine Umax, 0min, Gav, (rxy)max for this situation.

(e) Brieﬂy explain the role of idle gears in a simple gear train, with the help of neat sketches.

(0 List two temporary fasteners and explain the working of one of these.

(g) The state of stress at a point in a loaded machine member is given by the principal stresses _
0'1 = 600 MPa, 0'2 = 0 and 63 = — 600 MPa.
(i) What is the magnitude of the maximum shear stress ?

(ii) What is- the inclination of the plane on which the maximum shear stress acts with respect to the plane 'on which the maximum principal stress 61 acts ?
(h) Two long columns are made ,of identical lengths ‘l' and ﬂexural rigidities ‘EI’. Column 1 is hinged at both ends whereas for column 2 one end is ﬁxed and the other end is free.

(i) Write the expression for Euler’s buckling load for column 1.
(ii) What is the ratio of Euler’s buckling load of column 1 to that of column 2 ?

(i) A close coiled helical spring made of wire diameter d has mean coil radius R, number of - turns n and modulus of rigidity G. The spring is subjected to an axial compression W.

(1) Write the expression for the stiffness of the spring.
(2) What is the magnitude of the maximum .shear stress induced in the spring wire neglecting the curvature eﬂ'ect ?
