Two parts of a machine are held together by bolts that are initially tightened to provide a total of initial clamping force of 12,000 N. The elasticities are such that kc = 4 kb: (a). What external separating force would cause the clamping force to be reduced to 800 N (assume that the bolt remains within elastic range)? (b). If this separating force is repeatedly applied and removed, what are the values of the mean and alternating forces acting on the bolts? Show details
