racted space demands smallsize. Example. The overhungcrank of a steam engine shownin Fig. 70 has a force of 32,000lbs. acting at the center of the crank pin. Assume S equal to 10,000lbs. per sq. in. and calculate the diameter of the crank shaft. Solution. This is an example of combined bending and… … 3ZOOOO Fig. 71. Triangle of Forces T. = M + VM2+ TAT 1 MT = 6 X 32000 = 192000= 10 X 32000 = 320000 The value V M2 + T2 may be found graphically by using a righttriangle. Then drawing a right triangle to a scale such that one legis proportional in length to 192,000 and the other to 320,000, as…
