94. Analyzing the forces tending to drag the M = 5124 kg stone down the oak beam, we find FM g s =+ sin cos θμ θ b g where μ s = 0.22 (static friction is assumed to be at its maximum value) and the incline angle for the oak beam is . 1 39 10 23 b g (but the incline angle for the spruce log is the complement of that). We note that the component of the weight of the workers ( N of them) which is perpendicular to the spruce log is
