In physics, you can use the verticalloop velocity equation to determine the speed needed to go around a vertical loop. You can also use it to determine the diameter of, for example, a rollercoaster loop. Here are some practice questions that you can try. Practice questions A .
Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular crosssection were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...
