AMS 2011 previous year questions (Advanced Mechanics of Solids )

B.Tech (ME) 2011  Advanced Mechanics of Solids  (AMS) Previous year questions


Q.1 Compute the largest value of radial and hoop stress for a rotating disc of internal diameter 150mm and external diameter 300mm. The disc is rotating at 1500 rpm. for the disc material, density ρ = 7000 kg/m3 and v=0.3

Q.2 Prove that thickness of a disc of uniform strength is given by
       t = t0 exp-ρw2r22σ
      Where t0 is the thickness at r = 0

RTU Machenical engneering Advanced Machanics of Solids previous year questions 2012

The displacement field for a body is given by :
B.Tech, Advanced Machanics of Solids

 u = K(x2+y)i+K(y+z)j+K(x2+2z2)KWhere K = 103
At a point P(2,2,3), Cnsier two line segments PQ and PR having the following direction cosines before deformation.
PQ: nx1 = ny1 = nz1 = 13PR:nx2 = ny2 = 12, nz2 = 0
Determine the angle between the two segments before and after deformation.
2012

If the displacement field is given by.
B.Tech, Advanced Machanics of Solids

  Ux=Kxy, Uy=Kxy, Uz=2K(x+y)z
Where K is a constant small enough to ensure applicability of the small deformation theory.
1. Write down the stress matrix.
2. What is the strain in direction nx = ny = nz = 13
