A tree-trunk may be modelled a cylinder of diameter 30 cm and height 17.1 m. Video from a violent windstorm shows the tree bending so that the top of the tree trunk is shifted horizontally about 0.86 m. Given that wood has a Young's modulus of 50 MPa and a shear modulus of 15 MPa. Determine the force the wind exerts on the tree.

1. A ship weighing 7200 tons has a KG of 5.20 m, a KB of 3.12 m and a KM of 5.35 m. In the voyage, has used 300 tons of fuel with Kg 0.6 m. If the free surface effect is neglected and assuming KM remains constant, calculate the angle of inclination of the ship.
In principle, it is possible to use rotating cylinders as aircraftwings. Consider a cylinder 30 cm in diameter, rotatingat 2400 r/min. It is to lift a 55-kN airplane cruising at100 m/s. What should the cylinder length be? How muchpower is required to maintain this speed? Neglect end effectson the rotating wing.

A wind turbine with two or four hollow hemispherical cups connected to a pivot is commonly used to measure wind speed. Consider a wind turbine with four 8-cm-diameter cups with a center-to-center distance of 40 cm, as shown. The pivot is stuck as a result of some malfunction, and the cups stop rotating. For a wind speed of 15 m/s and air density of 1.25 kg/m3, determine the maximum torque this turbine applies on the pivot.

A windmill turns a series of slender rods fixed about one end . They are initially 2 meters long, and go at a speed of 15 revolutions per minute. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?
