ackings are placed in the Joints, then amuch larger margin should be made, for the maximum load whichmay come on the bolt is I -!- W, where W is the proportionalshare of the internal pressure carried by the bolt. In such casesS = 3,000 to 5.000, using the lower.value for bolts of less than|-inch… … Fig. 56a. may assume the length of the handle of an ordinary wrench, meas-ured from the center of tha bolt, as about 16 times the diameterof the bolt. For one turn of the wrench a force F at the handlewould pass over a distance 2TrI, and the work done is equal to theproduct of the force and space,…
