However, the tangential force that was applied to the body was known since Newton due to the rotation motion of the earth.
Therefore, the tangential force on the blades is .
These tangential forces cause distortion in the region where they first come into contact, followed by a region of slippage.
Mr. Weiss's cleats are attached with an adhesive, so they break off when under pressure from a strong tangential force.
In this case, if the tangential force is reduced then the elastic deformations and shear stresses reduce as well.
It is the tangential force which spins the motor.
We really want to know the tangential force pulling the blade around, and the radial force acting against the bearings.
A tangential force of 100 pounds force (400 N) is sufficient to start the antenna in motion.
Furthermore, the normal and axial forces will have no effect, so tangential force must be provided by friction.
To change its rate of rotation, some tangential force must be applied to its skin.
