FRICTION — APPLICATIONS TO MACHINES 117 Exercise 165. Explain the nature of the reactions whenthe line of action of the resultant load W (Fig. 88) passes thruthe intersection (a) at D; (b) at £; (c) when the line ofaction of the resultant Ues between C and B. In Fig. 88 note that the reactions at A… … Fig. 89 Exercise 166. (a) Show that if the distance betweenthe line of action of the resultant W and the center Kne of the rod (Fig. 88) is equal to or greater than —j where ij. is the 2 fi coefficient of friction and b is as indicated in the figure, then motion is impossible. (b) Should the…
