A recording tape passes over the 20-mm-radius drive drum B and under the idler drum C. Knowing

Question:

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 Î¼s = 0.40 and Î¼k = 0.30 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.
