DYNAMICS OF TIRE PRESSURE.SUBMITTED BY:CLASS (COURSE) NAME:TUTOR (PROFESSOR):SCHOOL NAME:THE CITY/STATE:DATE:
AbstractEvery vehicle has wheels in which most of them are made up pneumatic tires. Car wheels weremade many years ago with the enhancements and inventions of the pneumatic tires for conceivingcomfortable and fast road vehicles[ CITATION Bas04 \l 1033 ]. The primary features of a given tire are itssmall mass and flexibility, allowing the contact with the tire path to be sustained on uneven or evensurfaces. Furthermore, the rubber ensures high grip[ CITATION Gui14 \l 1033 ]. The features mentionedabove arises from the highly composite structures of tires: flexibility of carcass, yet relatively inextensiblecords encased in a matrix of flimsy rubbers inflated with air[ CITATION Gui14 \l 1033 ]. Provided that thetire is inflated properly, it may exchange along the bead appropriate actions with the rim. The loadsupport, steering, braking, and traction the net result.Also, the effect of air pressure increases the structural stiffness of the tire, but not directly tosupport the rim[ CITATION Cri15 \l 1033 ]. This report aims to investigate the pressure exerted by the tiresof a car on the road and the pressure of the air in the tires, then comparing it with measured value usingthe pressure gauge.

1.Introduction.If the car tire is inflated properly, figure 1.0 shows how given tire carries its mass. As shown in thefigure, the lower parts, the sidewall, and air pressurePaapplies vertical forcesFain the bead area morethan in the upper parts. Taking the overall effects on the rim is a vertical loadFz. If the air pressure, pa isincreased, the sidewall bending is reduced[ CITATION Bas04 \l 1033 ]. The pressure of the tire on the roaddepends on many factors, among them are the mass of the vehicle (that is the forces applied to the tire),tire characteristics such as the footprint (also called contact patch)[ CITATION Gui14 \l 1033 ][ CITATIONCri15 \l 1033 ]. The contact patch is the area of the tread in contact with the road surface. It is the area thattransmits forces between the tires and the road through friction and pressure[ CITATION Gui14 \l 1033 ].Other factors affecting road vehicle is the mechanical operation of the wheels, grip, and road roughnesseffects. The mechanical behavior of the wheels is the relationships between the force exerted by the roadand the kinematics of the rigid rim.Figure 1.0: How a tire carries a vertical load[ CITATION Bas04 \l 1033 ]Gripis thecontacts between two surfaces which are the road surface and the tire surface. Gripdepends on the types of road surface[ CITATION Woo13 \l 1033 ][ CITATION Cri15 \l 1033 ],roughnessof the contact, wetness and many other effects. Specifically, grip is defined by the
