Suppose the spring/balance device in Figure P13.10 is adjusted so that the spring is slightly stretched and the balance arm is level when the device is in an elevator at rest relative to the ground and a \(1.0-\mathrm{kg}\) object is placed as shown. If the elevator accelerates upward, does the balance arm tilt clockwise, tilt counterclockwise, or remain level?
