A wind turbine with a blade length of 5 m generates a lift force of 2000 N at a wind speed of 15 m/s. Calculate the coefficient of lift if the air density is 1.225 kg/m³.
💡 Hint: Calculate the area of the turbine blades first.
Explain how changing the shape of a bicycle helmet influences the aerodynamics and thereby the lift and drag experienced by the rider.
💡 Hint: Think about how shapes create turbulence.
