A square with the dimensions of .02m by .02m by .5m is attatched to a solid surface. If the forces on the rod are too large, it will either crush or be sheared off where it is atatched to the solid surface. If the rod can withstand either a maximum normal stress of 25kPa or a maximum shear stress of 10kPa
a) what is the largest allowable magnitude of F2 if F2=0?
b) what is the largest allowable magnitude of F2 if F1=0
