Question

A rectangular polymer plate of dimensions a = 163 mm and b = 371 mm is formed by gluing two triangular plates as shown in the figure. The plate is subjected to a tensile normal stress of 10.7 MPa in the long direction and a compressive normal stress of 5.6 MPa in the short direction. Determine: (a) the normal stress perpendicular to the glue seam. (b) the shear stress parallel to the glue seam. (a) Enter the normal stress $\sigma_n$, perpendicular to the glue seam. This is the normal stress in the $n$ -- direction which is normal to the inclined plane as shown in the figure below. Use the correct sign based on the sign convention for normal stress. $\sigma_n = $ MPa (b) Enter the shear stress parallel to the glue seam. Your answer must be consistent with the sign convention for shear stresses and the $n$ -- $t$ coordinate system shown in the figure above. $\tau_{nt} = $ MPa

(a) Enter the normal stress , perpendicular to the glue seam. This is the normal stress in the n – direction which is normal to the inclined plane as shown in the figure below. Use the correct sign based on the sign convention for normal stress.
= MPa
(b) Enter the shear stress parallel to the glue seam. Your answer must be consistent with the sign convention for shear stresses and the n – t coordinate system shown in the figure above.
τnt = MPa
