Required information
A recording tape passes over the 20-mm-radius drive drum B and under the idler drum C.
A
$T_A$
D
M
Knowing that the coefficients of friction between the tape and the drums are $\mu_s$ = 0.40 and $\mu_k$ = 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. Given: M = 0.5 N-m. (Round the final answer to three decimal places.)
The smallest allowable value of P if slipping of the tape on drum B is not to occur is N.
