Please help me solve this problem.
Calculate the total torque (magnitude and direction) for each of the following cases shown below. You can assume the "bar" the masses are attached to is massless. The top point of the triangle represents the pivot point for the system. Be sure to include the magnitude and the direction. (a) Here m = 6 g and d = 20 cm. magnitude 07058 NmX direction --Select- (b) Here m = 6g and d = 20 cm. magnitude direction -Select- = m2 = 5 g and d = dy = 20 cm. (c) Here m magnitude direction --Select- - m - 6g and d. = 20 cm and d = 1.5 m. (d) Here m magnitude direction Select-
