Chapter 8, Problem 29P
The friction pawl is pinned at A and rests against the wheel at B. It allows freedom of movement when the wheel is rotating counterclockwise about C. Clockwise rotation is prevented due to friction of the pawl which tends to bind the wheel. If, (μs)B = 0.6, determine the design angle θ which will prevent clockwise motion for any value of applied moment M. Hint: Neglect the weight of the pawl so that it become a two-force member.
