# Question 5 ft 7.84 Find the smallest angle B for which the uniform crate can be tipped about corner A. Also compute the corresponding value of P oo o 5 ft 200 lb P 7.85 The belt is placed between two rollers whieh are free to rotate about A and B. Determine the smallest coefficient of static friction between the belt and the rollers for which the device is self-locking; that is, the belt cannot be pulled down for any value of P ooo o A As= 0.2 Fig. P7.84 Belt 6H1K5C The Asker · Civil Engineering
