Flower Fg.dir The dirt pushes down on the shovel at the very end of the shovel, as shown in the diagram. What is the angle between the dirt's force vector and the lever arm vector used to calculate the torque? 470 What is the direction for the torque from the dirt? Negative (into screen) The boy pulls straight upward on the shovel with his lower hand, as shown in the diagram.
