Final answer:
The correct option is a) Yes, it shifts upward.
When picking up a load with a forklift, the center of gravity shifts. The direction of the shift depends on whether the load is balanced or unbalanced.
Step-by-step explanation:
When picking up a load with a forklift, the center of gravity does shift. The direction of the shift depends on whether the load is balanced or unbalanced. In most cases, when picking up a load, the center of gravity of the forklift and the load shift downward. This is because the weight of the load is added to the overall weight of the forklift, causing the center of gravity to move closer to the ground.
However, if the load being picked up is unbalanced, the center of gravity may also shift upward or to one side. This is because an unbalanced load creates an uneven distribution of weight, causing the center of gravity to move in the direction of the heavier side. In this case, the forklift operator needs to take extra precautions to ensure stability and prevent the forklift from tipping over.
