The antenna on a car is 10 mm in diameter and 1.8 m

long. Estimate the bending moment that tends to snap it off

if the car is driven at 120 km/hr on a standard day.

A large three-blade horizontal axis wind turbine

(HAWT) can be damaged if the wind speed is too high.

To avoid this, the blades of the turbine can be oriented

so that they are parallel to the flow. Find the bending moment at the base of each blade when the wind

speed is 85 knots. Model each blade as a flat plate 115 ft

wide 3 1.5 ft long.
