A civil engineer in Boulder, Colorado, estimates that under the severest expected Chinook winds, the total force on the highway sign will be F = 2.8i – 1.8j (kN). Let MO be the moment due to F about the base O of the cylindrical column supporting the sign. The y component of MO is called the torsion exerted on the cylindrical column at the base, and the component of MO parallel to the x-zplane is called the bending moment. Determine the magnitudes of the torsion and bending moment.
