How does engineers calculate drag force on a surface(eg. autobody/airfoil)?
Answer:
How can I measure the drag on a car?
I have to think of a way of measuring how much drag is pushing on my mother’s car as we are driving on the highway. Do you know how I can make one?.., there is a relatively simple way to learn how much drag is on your car. In the article How Force, Power, Torque and Energy Work you learned about Newton...
