|  | 31. | In 1953 she accepted an offer to work for engineer drag forces, in order to improve United States planes. 
 
 | 
|  | 32. | Spin ( rotation ) has little influence on lift and drag forces but impacts a disc's stability during flight. 
 
 | 
|  | 33. | The analysis shows that, other things being equal, the drag force will be proportional to the density of the fluid. 
 
 | 
|  | 34. | Thus the moving conductor will experience a drag force from the magnet that opposes its motion, proportional to its velocity. 
 
 | 
|  | 35. | For instance, in physics of sports, the drag force is necessary to explain the performance of runners, particularly of sprinters. 
 
 | 
|  | 36. | The turbine drag forces are therefore transmitted through a bearing system linking the fixed and rotating parts of the buoy. 
 
 | 
|  | 37. | Eddy current brakes use the drag force created by eddy currents as a brake to slow or stop moving objects. 
 
 | 
|  | 38. | When the front velocity increases, this film thickness " ( d ) " will decrease due to increasing drag forces. 
 
 | 
|  | 39. | Refer to the Airfoil article for more information on how airfoils create lift and drag forces at various angles of attack. 
 
 | 
|  | 40. | The basic principle of separating the cells inside CCE is the balance between centrifugal force and the counter flow drag force.
