In a concrete mixer, cement, gravel, and water are mixed by tumbling action in a slowly rotating drum. if the drum spins too fast the ingredients stick to the drum wall instead of mixing. assume that the drum of a mixer has radius r = 0.5 m r=0.5m and that it is mounted with its axle horizontal. what is the fastest the drum can rotate without the ingredients sticking to the wall all the time? assume g = 9.8 m / s 2 g=9.8m/s2.
