A recording tape passes over the 20-mm-radius drive drum B and under the idler drum C
Chapter 8, Problem 8.124(choose chapter or problem)
A recording tape passes over the 20-mm-radius drive drum B and under the idler drum C. Knowing that the coefficients of friction between the tape and the drums are 0.40 s = and 0.30 k = and that drum C is free to rotate, determine the smallest allowable value of P if slipping of the tape on drum B is not to occur.
