An element is acted upon by the following stresses: \sigma _(x)=1500 psi,\sigma _(y)=22500 psi , and \tau _(\tau v)=-10000 psi.
(a) By means of the equations compute the stresses on the sides of an element oriented 30\deg clockwise with the x-axis.
(b) Find the value of \phi for maximum and minimum normal stress and compute the values of these stresses.
(c) Repeat part (b) for maximum shear.
(d) Make a view showing the given state of stress, and draw the corresponding Mohr circle. Scale the stresses for the element oriented 30\deg from the x-axis, and compare them with the results secured by use of the equations. Draw a view of this element with the stresses placed thereon
(e) Scale the values of the maximum and minimum normal stress and represent them by arrows on an element oriented at the proper angle.
(f) Repeat for the element that is subjected to the maximum shearing stress.
Ans. Max\sigma =26500 psi;max\tau =14500 psi.
