Torque and Rotational Motion

Torque and Rotational Motion

Introduction

Rotational motion is quite affected by the use of rotational resistance (in the form of frictional force provided from the surface) from the rotational speed. Under the condition where the system under quite high Mach number, the design consideration becomes quite crucial to analyze as well as develop a system free of flaws and loopholes. The incorporation of rolling resistance is also quite commonly discussed under the domain of mechanical engineering as well as physics. The assignment will look into the very principles which are responsible for the determination of rolling speed, as well as resistance.

The previous assignment has surely provided us with quite an insight of before landing scenario, which has facilitated to attain a better understanding about the smoke caused by the landing gear deployment. The wheel torques and bearing torques were also used in connection with the various other parameters; like, angular acceleration, angular velocity, and most importantly the mass moment of inertia.

The rotational motion is quite commonly hindered by the incorporation of frictional resistances. The frictional forces tend to hinder the rotational motion of the rear tires as in the case of aircraft and other vehicles. The aircraft surely face severe consequence due to the frictional condition and tends to make the phenomenon of flat-proofing prominent. Rolling friction is produced by the interference of the surface roughness thereby causing the reduction in the performance of aircrafts and also reduction in approach speed, which will be witnessed in prior calculations. However, it is better in some cases too. The most prominent advantage, which we can attain from the rolling friction is that it will facilitate us with the provision of excellent traction of the wheel and the runway. Moreover, the friction causes the wheel to seize its rotational motion (resulting in decline of angular and linear velocities) thereby causing a reduction in skidding action of the tires (Phy.Davidson.edu, 2013).

Rolling friction is quite diversified and requires the ample knowledge of mechanics behind the way in which the forces act and behave. There are two broad scenarios related to slip and no-slip phenomenon. During the no-slip, the common equation of linear velocities and acceleration are applicable. On the other hand, in the slip condition, the equation are not applicable and require separate line of action to tackle such real-world problems deviating from the ideality behavior of no-slip condition. The kinetic frictional forces are used to explain the phenomenon of friction as well as the resistances which are commonly encountered. The rolling resistance also has to deal with the determination of the coefficient of friction along with the normal reaction which is acted on the ground.

The braking mechanism provided in numerous aircrafts also helps the plane to lower the speed beside the incorporation of frictional resistances. In turn, this helps the aircraft to reduce the slip effect which is quite prevalent in almost each and every vehicle on the face of the earth. The factor of various arresting systems ...
