ADDITIONAL CREDIT (3 mills) You can change the charge on the sliding ball by factors of two, by touching it to the other uncharged sliding ball (ground it with your finger first). The balls will share their charge, and half the charge will remain on the first ball (assuming the balls are the same size).

series of harmonics. For a single row radial ball bearing with an inner ring speed of 1800rev/min a typical ball pass rate is 100Hz and significant harmonics to more than 500Hz can be generated. Variable compliance vibration is heavily dependent on the number of rolling elements supporting the externally applied

In a rice mill machine, the rice grains directly interact with the hopper, rotating roller, rice sieve, and baffle, as shown in Fig. 1a, b. In the previous works, it indicates that the geometry of the rice sieve and the rotating speed were critical to the milling process, but few studies focused on the geometry of the rotating roller.

The bowling ball consists of some amount of energy in the form of kinetic energy as soon as it starts rolling towards the target. Due to this energy, the ball has the ability to do work on the pins. When the ball hits those target pins, it (ball) applies force (in the form of mechanical energy) and displaces them, hence, causing work to be done.
