ANSWER:
Step 1 of 4
In order for the cylinder to slip, sum of moments about point must greater than zero, i.e. the cylinder will be at the edge of slipping when the sum of moments about is equal to zero.Refer to the free body diagram below.
Note that frictions and are equal to the maximum static friction, since the cylinder is on the edge of slipping
