Programming in MATLAB:

8cm 14cm 16cm 10 M- 120Nm 1. Beams experience a normal stress of due to the bending moment M where My =-M cos 45 and M-=-M sin 45 are the y- and z-components of M respectively, and I,-736 cm and I-1584 cm for the given geometry. Use meshgrid to define the domain and generate a surface plot of the normal stress and include a colorbar. Be sure to remove the area inside the channel from the graph by detecting where the hole is rather than hard-coding index numbers, draw the y-z plane to scale, and include units as appropriate
