12. (a) Using the result obtained in Sample Problem 6-2, the maximum angle for which static friction applies is 11maxtantan 0.6332 .sθμ−−==≈°This is greater than the dip angle in the problem, so the block does not slide. (b) We analyze forces in a manner similar to that shown in Sample Problem 6-3, but with
