You are balancing a wrench by suspending it at a single point. Is the equilibrium stable, unstable, or neutral if the point is above, at, or below the wrench’s center of gravity? In each case give the reasoning behind your answer. (For rotation, a rigid object is in stable equilibrium if a small rotation of the object produces a torque that tends to return the object to equilibrium; it is in unstable equilibrium if a small rotation produces a torque that tends to take the object farther from equilibrium; and it is in neutral equilibrium if a small rotation produces no torque.)
