Besides the longitudinal additional force, the temperature force caused by the change of rail temperature is also reserved in rail. LONGITUDINAL RESEARCH. The effective distance a between the lateral forces F y,w,r,o and i on the wheels of the rigid axle and the force F T,Y on the panhard rod at the back leads to a force pair which generates the forces ± F x in the longitudinal links and can cause lateral force understeering due to the compliance of the rubber mountings. E Width of Saddle perpendicular to Longitudinal Axis Theta = 120. longitudinal stress: s r Considering that the pipe ends are closed and pipe is subjected to an internal pressure ‘P’ the pipe may fail as shown in Fig. In this model the longitudinal force, F XWij, and the slip angle, ij, on each wheel chosen as independent variables. force acting on the nth atom is ( 1 ) ( 1 ) (2 1 1) 2 2 Fn C un un C un un C un un un t u M equation of motion (nearest neighbors interaction only): M is the atomic mass, C – force constant Now look for a solution of the form u(x,t) Aei(qxn t) where xn is the equilibrium position of the n-th atom xn = na obtain 24 the dispersion relation is. The below mathematical formula is used in mechanical engineering to calculate the capacity of the pipe or cylinder to with stand the force developed along the longitudinal axis of the cylinder due to its closed ends & the internal pressure.
