The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. <br> <br>Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring‚ which have raceways‚ or slots‚ grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types

Projectiles Practical Report 1. Introduction Velocity is a vector measurement of the rate and direction of motion or‚ in other terms‚ the rate and direction of the change in the position of an object. [1] Velocity can be found many ways through various suvat Equations and their rearranged forms. For example v2=u2+2as in which the square of the final velocity can be found if you know the objects initial velocity‚ the acceleration and the distance travelled. Using such formulae makes it possible

Control Systems Lab Project (Ball and Beam) Ball and Beam Abstract The ball and beam system can usually be found in most university control labs since it is relatively easy to build‚ model and control theoretically. The system includes a ball‚ a beam‚ a motor and several sensors. The basic idea is to use the torque generated from motor to the control the position of the ball on the beam. The ball rolls on the beam freely. By employing linear sensing techniques‚ the information from the sensor
