Write a user-defined MATLAB function that determines the principal stresses from the stress components. For the function name and arguments use [Smax, Smin] = princstress (Sxx, Syy,Sxy). The input arguments are the three stress components, and the output arguments are the maximum and minimum stresses. Use the function to determine the principal stresses for the following states of stress: (a) , = -190MP,, o, = 145 MPa, and 1 = 110 MPa. (b) ở = 14ksi, o, = -15 ksi, and t, = 8 ksi. X.

please have it so I can copy and paste and please don't use the answer on another website. thank you

A two-dimensional state of stress at a point in a
loaded material is defined by three components of
stress o„„, , G,y, and t,. The maximum and mini-
mum normal stresses (principal stresses) at the point,
Omar and omia , are calculated from the stress compo-
nents by:
Try
