-dimensional equilibriumconsider the shaft represented in Fig. 59. A verticalforce of 100 poimds acts upon a horizontal crank 10 feetlong; the magnitude of a horizontal force acting ona vertical crank 5 feet long and the reactions of the bear-ings are required. As no force or component force acts… … Fig. 59 and Let the directions of these reactions be assumed as shownY,| in Fig. 59. As the system of forcesacting upon the shaft andcranks as a free body(Fig. 59) is in equilibrium,the sum of the forces (ortheir components) in thedirection of the three axesmust each separatelyequal zero. Thus,-LX…
