  Two uni-axial suspensions are shown in the figure below.
  Derive k_xx, k_yy and k_zz for both. Also derive, rotational stiffness about the z-axis for both.
• 30 points
  Use the beam finite element code and verify your analytical formulae derived in the previous problem using reasonable numerical data. By "reasonable", we mean that the geometric parameters and material properties should make sense from the viewpoint of micro/nano mechanical suspensions.
