Question 251 Deck General

The correct answer is B) decelerating when lowering the load. When lowering a load, the force acting on the cargo runner is greatest during deceleration. This is because as the load is being lowered, the downward acceleration of the load is being opposed by the upward force of the cargo runner. The greater the deceleration, the greater the opposing force on the cargo runner. The other options are incorrect because: A) when lowering the load at constant speed, the force on the cargo runner is constant; C) when decelerating while raising the load, the force on the cargo runner is reduced; and D) when raising the load at constant speed, the force on the cargo runner is constant.
