A rock impacts a traffic guardrail imparting a force of 650 N inclined at an angle 20 degrees from horizontal. The force acts over an area of 160 mm² on a segment of the guard rail that is oriented 45 degrees from horizontal. The y-axis shown in the figure is drawn perpendicular to the surface on which the forces are acting. Determine the average normal and shear stresses that are applied to this portion of the guard rail. 20⁰ F 4 45 x
