Solve Prob. 8.122 assuming that the idler drum C is frozen and cannot rotate. Problem 8.122: 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 μs = are 0.40 and μk = 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.
