The problem involves a rock being spun in a horizontal circle, where the tension in the string must not exceed a certain limit to avoid breaking. The subject area pertains to centripetal force and circular motion dynamics.
Some participants have provided feedback on the calculations and the presentation of the equations. There is ongoing clarification regarding the relationship between tension and period, with no explicit consensus reached yet.
Participants note that the equation used is from the textbook, and there is some confusion regarding its presentation. The discussion also highlights the constraints of the problem, particularly the maximum tension limit.
anaximenes said:Your equations written as pie squared r instead of pie r squared, i think you did it right but it looks weird
Yes, the equation is correct, though it does look odd at first sight.Lax0 said:its the equation in the textbook.
The stone has a certain distance to cover, 2πr, in one period. So minimum period means maximum speed, and that means maximum tension.So can you explain how max tension gets minimum period?
