The extensional strain of the longitudinal elements of the beam is the most important strain component in pure bending. This relation was first given by Newton and therefore it is known as Newton's formula for the speed of sound. Shear forces on beams are largest at the supports, and the shear force at any distance x from a support. So a fighter operating at up to 9-g or more needs a shallower force-per-g gradient than a transport expected to operate at no greater than the 1. Colour strong force. The tyre lateraland longitudinal forces are introduced using the Magic Formula Tyre Model which features the use of weighting functions to account for combined slip conditions [11]. Each of these stresses will be discussed in detail as follows. However, in Moens–Korteweg's formula or many other modified formulae, the stiffness is counted through the Young's modulus of elasticity related to the circumferential stretching, while our formula indicates that PWV is mainly associated with the Young's shearing modulus and the longitudinal tension of the blood vessel.
