Question

The plank of negligible mass is shown in the figure and is pivoted about the indicated point. Two upwardly directed forces act on the plank. A force of magnitude F1-35.7 N acts at one end of the plank at a distance of x167.3 cm away from the pivot. A second force of magnitude F2=14.9 N acts at the opposite end of the plank at distance of x2 = 27.5 cm from the pivot, what is the size of the net torque on the plank about the pivot? Г. PIVOT Submit Answer Tries 0/5

{ take clock wise as (-) and antilock wise (+) torque produce by F_1 = 35.7 times 0.673 in clockwise = 24.0261 Nm torque produce by F_2 = 14.9 times 0.275 m, in Antilock wise = 4.0975 (+) Resultant torque = -24.0261 + 4.0975 = -19.9286 in (clock wise)
