the top of the rotating blade is at 282 meters, and the bottom is at 118 meter which is a 2.4 to one ratio. So there is a top to bottom wind shear well known to sailboat sailors, and the wind axial thrust will vary as the square of that ratio. so the blades will flex back and forth axially at the rotation rate.Distinguish Between Bearing And Crushing Stress. What is difference between shearing stress and crushingwhat is difference between shearing stress and crushingDifferentiate between shearing and crushing shear stress tends to slide the material particles while crushing stress compresses the material, distinguish between bearing and crushing stress
