If e = 15°, what is the frictional force between the block and the incline? (N) C. If e = 25°, what is the frictional force between the block and the incline? (N)
Im able to break down each component of AB. AC and AD. getting lengths and angles. But im not sure how to approach breaking down how the force is devided through each. I'm not sure how to show that even though AB and AD are the same distance and at the same angle from point A they dont share the same forces. I do know this problem should be solved by finding which rope would hold the most tension because that would be the first one to fail. Then we solve for the rest of the problem assuming that the tension on this rope is 690 to find the maximum possible net force.
