Company Z is having problems with the press shown in figure No.3. The company has informed us that the press has a tightening capacity of 5500 Ib. This uses a 3-inch square thread screw outside diameter and four threads per inch. They are interested in obtaining the following data, + to be able to see why they fail and in what f part: ac The required force to be applied in 12-inch diameter crank. Assuming that the coefficient of friction of the thread and collar is 0.125 and =2.5 inches b. The efficiency of the screw. c. The size of the two bolts required to support the base. Assume that the allowable bolt strength is 8,000 lb/pug2 and which are fine threaded.
