Homework Statement


In the figure a sled being held on an inclined plane by a cord pulling directly up the plane. The sled is to be on the verge of moving up the plane. In the lower figure data is plotted with the magnitude F required of the cord's force on the sled is plotted versus a range of values for the coeffient of static friction μs between sled and plane. F1 = 10.50 N, F2 = 26.25 N, and μ2 = 0.290. At what angle θ is the plane inclined? (deg)

Homework Equations




The Attempt at a Solution

I've tried pretty much everything i can think of on this problem and can't seem to get any answer that makes sense. I tried to set the acceleration equal to zero but i kind of think that in order to find the angle i would need the greatest static friction possible but i dont really know how to do that.

Cannot see the figure as it requires a login ID.
