1. A 22 in. by 34 in. speed limit sign is supported on a 3-in.-wide, 5-ft-long pole. Estimate the bending moment in the pole at ground level when a 30-mph wind blows against the sign. (See Video V9.14.) List any assumptions used in your calculations.
2. Determine the moment needed at the base of a 20-mtall, 0.12-m-diameter flag pole to keep it in place in a 20-m/s wind.
