High-strength bolts are used in the construction of many steel structures. For a 1-in.- nominal-diameter bolt, the required minimum bolt tension is 51 kips. Assuming the coefficient of friction to be 0.30, determine the required couple that should be applied to the bolt and nut. The mean diameter of the thread is 0.94 in., and the lead is 0.125 in. Neglect friction between the nut and washer, and assume the bolt to be square-threaded. You must show a free body diagram of your block and incline analysis of the bolt and nut, and clearly indicate your force triangle, if any.
