Now consider a small square in the section around po P. Sketch the normal and shear stresses that are nonzero on this element below. The orientation of your vectors will be graded. The exact length of your vectors will not be graded. Make sure all of the vectors start at the black dot. tauvectzy : shear stress tau_zy tauvectzz : shear stress tau_zz tauvectyx : shear stress tau_yx sigmavectz : normal stress sigma_z sigmavecty : normal stress sigma_y tauvectyz : shear stress tau_yz tauvectxy : shear stress tau_xy sigmavectx : normal stress sigma_x tauvectxz : shear stress tau_xz unlabeled vector Solution only sigma_z , tau_zy , tau_zx will act on the given element... .
