The coefficient of friction between block $m$ and block $2 m$ is $μ = 2 tan θ$ . There is no friction between block $2 m$ and the incline. The maximum amplitude of the two-block system for which there is no relative motion (Figure 5.103) is:

About equilibrium the common acceleration is k x /3 m . On m the friction is f = m ( g sin θ + a ) taking up-slope as positive, and f cannot exceed μ m g cos θ = 2 m g sin θ in magnitude. The binding case is a = g sin θ (up the slope), so k A /3 m = g sin θ and A = 3 m g sin θ / k .
