The longitudinal axis of a beam is aligned with the $\mathrm{x}$ axis. The beam has a triangular cross-section, as shown above. The loading on the beam produces the bending moment diagram for $\mathrm{M}(\mathrm{x})$ shown above. a) Provide the $x$ - $y$ coordinates of the point on the beam that experiences the largest magnitude compressive normal stress. b) Provide the $x$ - $y$ coordinates of the point on the beam that experiences the largest magnitude tensile normal stress.
