JNTU previous question papers 2-1 mechanical

Hi guys, I am doing B.Tech Mechanical Engineering from JNTU (Jawaharlal Nehru Technological University), this year I have filled form for 2nd year 1st semester exam, so can you provide me last few year question paper with solution for preparation of my examination?

here I am giving you papers name of B tech 2nd year 1st semester for the mechanical engineering course offered by the JNTU below :
B tech 2nd year 1st
MECHANICS OF SOLIDS

1. (a) Derive relation between three elastic moduli [8]
(b) Draw stress - strain diagram for mild steel. Indicate salient points and define
them. [8]

2. A hollow cylinder of internal and external diameters of 12.5 cm and 25 cm and
a length of 50 cm is stressed to 840 N/mm2 by an axial load. The modulus of
Elasticity of the material is 2×105N/mm2, while its Poisson’s ratio is 0.25. Find
the change in [16]
(a) its internal dimensions
(b) change of internal volume and
(c) the proportional change in its density.

3. (a) Device the relations among loading, shear force and bending moment in a
beam. [9]
(b) A cantilever beam AB span 6m is subjected to a uniformly varying load of 8
kN/m intensity at the fixed end A and zero at the free end B. draw SFD and
BMD. [7]

4. (a) Discuss the assumptions involved in the theory of simple bending. [6]
(b) The cross section of a simply supported beam is as shown in Figure 4(b)iii.
Find its moment of resistance if permissible tensile stress is 160MPa. Compare
it with equivalent section of same area but [10]
i. Square section
ii. Rectangular section with twice the width and
iii. a circular section.

5. (a) A beam of length L is supported at each end with a couple applied at an intermediate
point. Deduce an expression for the deflection and hence calculate
the deflection at the point of application of the moment. [8]

(b) A beam of length L carries a uniformly distributed load w/unit length and
rests on three supports, two at the ends and one in the middle. Find how much
the middle support be lower than the end ones in order that the pressures on
the three supports shall be equal. [8]

7. (a) Derive an expression for the stresses on an oblique section of a rectangular
body, when it is subjected to a direct stress in one plane only . [6]
(b) The principal stresses at a point in a member subjected to two dimensional
stress are 120 N/mm2 and 50 N/mm2 tensile. Find the plane on which the
resultant stress has maximum obliquity and magnitude of this obliquity. [10]

8. A propeller shaft, 160mm external diameter, 80mm internal diameter, transmits
450kW at 4/3 Hz. There is, at the same time, a bending moment of 30kN-m and
an end thrust of 250kN. Find [16]
(a) the maximum principal stresses and their planes
(b) the maximum shear stress and its plane

for the complete question paper I am attaching a link with it ..
