1. A vertical force of 80lb acts on the crankshaft. Here, the crankshaft is supported by a journal bearing A and a thrust bearing B. The two bearings A and B are properly aligned. Determine the horizontal force P that keeps the crankshaft at rest. Also determine the reactions at bearings A and B. (P-100lb, A, 135.7lb, Az-40 lb, B=0, By=-35.7 lb, B=40lb). 2. P sy p₁ D fo 80 lb -10 in. B 8 in. 14 in. 6 in. 4 in. 14 in.
