A fishing rod is made of glass-fiber-reinforced plastic in the form of a tube having an outer diameter of 10 mm and a wall thickness of 1.5 mm. The glass fibers are par- allel to the tube axis, so that the bending shear stress is carried by the plastic and the bending stresses are car- ried by the fibers. The fishing rod is 2 m long. Determine whether the rod fails from tensile stresses in the fibers or from shear overstressing in the plastic. The bending strength of the fiber-reinforced plastic is 800 MPa, and its shear strength is 3.2 MPa.
