###### 1.Accuracy of solution in a 2‐D component depends on
• Included angle of elements
• Size of the component
• No. of d.o.f /node
• Type of load
• 3x3
• 4x4
• 6x6
• 9x9
• 2
• 3
• 4
• 5
###### 4.A 3‐D dam is usually modeled with
• 2‐D plane stress elements
• 2‐D plane strain elements
• 3‐D solid elements
• 3‐D shell elements
###### 5.An element with in‐plane loads having 3‐nodes along each side is a
• Constant strain element
• Linear strain element
• Quadratic strain element
• Constant displacement element
• Lagrangian
• Poisson
• Gaussian
• Jacobian
###### 7.A symmetric structure can be analysed by modeling one symmetric part
• Depending on applied loads
• Depending on boundary conditions
• Always yes
• Depending on applied loads & boundary conditions
###### 8.Gaussian points are used for
• Numerical integration
• Displacement calculation
• Stress calculation
• Strain calculation
###### 9.Principal modes of vibration of a multi‐degrees of freedom system are
• Parallel
• Orthogonal
• Inter multiples
• Fractional multiples
###### 10.With lumped mass matrix, the differential equation of vibration refers to
• Elastic coupling
• Inertia coupling
• Mode superposition
• Both (a) and (b)
