Energy Method 6:

Taking into account only the effect of normal stresses, determine the strain energy of the prismatic beam AB for the loading shown (Picture 6).

Energy Method 7:

Using E = 200GPa, determine the strain energy due to bending for the steel beam and loading shown. (Ignore the effect of shearing stresses.) (Picture 7)

Energy Method 8:

Rod AC is made of aluminum and is subjected to a torque T applied at C. Knowing that G = 73GPa and that portion BC of the rod is hollow and has an inner diameter of 16mm, determine the strain energy of the rod for a maximum shearing stress of 120MPa. (Picture 8)

Energy Method 9:

The state of stress shown occurs in a machine component made of a brass for which s_y = 160MPa. Using the maximum-distortionenergy criterion, determine the range of values of s_z for which yield does not occur (Picture 9) .

Energy Method 10:

Determine the strain energy of the prismatic beam AB, taking into account the effect of both normal and shearing stresses (Picture 10) .
