Dima pulls directly backward with a force F = 161 N on the Side view end of a 2.00 m-long oar. The oar pivots about its midpoint. At the instant shown, the oar is completely in the yz-plane and makes a 0 = 37.0' angle with respect to the water's surface. Derive an expression for the torque vector 7 about the axis through the oar's pivot. Express the torque using ijk vector notation. 7 = trittj+uk Enter numerical values with three significant figures. Aerial view 7 = N.m F X
