Measure the distance across the shaft hole of the pulley with a measuring tape. Divide this by two with your calculator. If the shaft hole is 1 inch wide, then: 1 divided by 2 equals 1/2. Add the distance from the edge of the shaft hole to 1/2 the distance across the shaft hole: 6 plus 1/2 equals 6 1/2. Multiply the result by 2: 6 1/2 times 2 equals 13, the size of the pulley. A 13-inch pulley is suitable for use with ropes 1.6 inches in diameter, or line commonly sized as 1 1/2-inch line.
Different materials have different values of work function. Generally, elements with low I.P values have low work function such as Li, Na, K, Rb, and Cs. The negative potential of the plate 'C' at which the photo electric current becomes zero is called stopping potential or cut-off potential. Stopping potential is that value of retarding potential difference between two plates which is just sufficient to halt the most energetic photo electrons emitted.
Cancer cells are uniquely able to signal cell cycle progression without the binding of external stimuli. This action is likened to driving a car without first pressing the gas pedal. Ignore Stop Signals. The cell cycle utilizes the checkpoint system to immediately halt the process of cell division if a problem is encountered. The system has inborn stop signals. A primary deterrent to cell division is damaged DNA. A normal cell will not continue to advance through the G1, M and G2 phases if its DNA became damaged.
