MHB Calculate the rotational frequency in r/s and the diameter of the drive pulley

Click For Summary
The discussion focuses on calculating the rotational frequency in revolutions per second (r/s) and the diameter of a drive pulley based on a belt speed of 33 m/s and a pulley rotation of 750 r/min. The rotational frequency can be determined by converting 750 r/min to r/s, resulting in 12.5 r/s. To find the diameter of the drive pulley, the relationship between linear speed, rotational frequency, and diameter is used, leading to a calculated diameter of approximately 0.84 meters. Participants are encouraged to share their methods and calculations for verification. The thread emphasizes the importance of applying relevant formulas to solve the problem effectively.

a belt is driven by a pulley at 33m/s the pulley rotates at 750 r/min. calculate:

(a) the rotational frequency in r/s

(b) the diameter of the drive pulley

Thread 'Significant figures for inherently bound values'

I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
