If normal stress in the x direction is 10 ksi tension, normal stress in the y direction is 30 ksi compressive,
and there is 10 ksi (ccw) of shear stress, then:
a) (20) Draw the stress state diagram and label all pertinent data
b) (30) Create a 2-d Mohr circle diagram using graphical methods. Explain, using words, how you
constructed the diagram. Draw the graph is accurate scale use graph paper. Label all pertinent
data, including the center of the circle (C), the circle radius (R), and both maximum and
minimum 2-d shear stress.
c) (30) Create a 3-d Mohr circle diagram using graphical methods. Explain, using words, how you
constructed the diagram. Draw the graph is accurate scale use graph paper. Use graph paper
and label all pertinent data, including all normal and principle stresses.
d) (5) The maximum 3-d principle normal stress is:____ksi
e) (5) The maximum 3-d principle normal stress is:____ksi
f) (5) The minimum 3-d principle normal stress is:____ksi
g) (5) The maximum 3-d shear stress is:____ksi
