Lecture 4, #3 PROBLEM DESCRIPTIONA mass m is attached by two strings (of negligible mass) to a central pole. The pole can rotate such that the mass makes a horizontal circle of radius R with constant speed v, with the strings at angle of 45o as shown in the figure. In terms of m, R, v, and constants, what are the tensions in the top and bottom string? |
