δ {\displaystyle \delta } is the displacement produced by the force along the same degree of freedom (for instance, the change in length of a stretched spring) In the International System of Units, stiffness is typically measured in newtons per meter ( ). In Imperial units, stiffness is typically measured in pounds (lbs) per … Ver mais Stiffness is the extent to which an object resists deformation in response to an applied force. The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is. Ver mais The stiffness, $${\displaystyle k,}$$ of a body is a measure of the resistance offered by an elastic body to deformation.

WebCornering Stiffness. A fundamental measure of the grip capability of a tyre in the lateral sense is known as the cornering stiffness. This is expressed as the force generated per degree of slip angle (N/ °).For a given slip angle, a tyre with a higher cornering stiffness will produce a greater lateral acceleration and this is a key performance measure of any tyre.
