Question
I would like to know if my logic for Prob. 36 is correct. Here is my solution:-
33· Determine beam reactions in Figure (f) above. Consider Ans, RA=2861b, RB - 1641b ends. How far from the left support should a concentrated load of 100 lb be placed so that the left reaction will be 85 lb? Ans. d 6 ft 34. A beam 8 ft long and weighing 15 lb per ft rests on supports at its Fig. i) P 40. In Pigure (j) reaction at A Ans. Ah = 34 35. In the adjacent figure, what force P is required to raise a weight of 200 lb at constant speed? Ans. P 100 lb W-200 o 1b in equilibriun 41. In the adjace shown acting one foot int kips. Determ B. Ans. 36. In Figure (g) below, what force P is required to hold a weight of 600 lb in e Ans. P 200 lb In Pigure (ch) below, a system of levers is shown supporting a load of 80 1b. Determine the actions at A and B on the lever. Ans. RA-71.1 lb, RB = +124 1b 37. In Pigure (h) below, a system of levers is shown supporting a load of 80 lb 42.
