The crate A of mass m and the wedge B on which it rests are both initially at rest. The wedge, whose face is inclined at θ = 30° with the horizontal, is given an acceleration aB to the left as shown. Given that the coefficient of static friction between the crate and the wedge is μs = 0.6, determine the maximum value of aB such that the crate does not slip on the wedge.
