Final answer:
Jack stands are not hydraulically operated like a hydraulic jack. They are mechanical devices that use a simple lever system to support heavy loads. They are light compared to the load they can support.
Step-by-step explanation:
Which statement regarding jack stands is correct?
Jack stands are not hydraulically operated like a hydraulic jack. They are actually mechanical devices that use a simple lever system to support heavy loads. When weight is applied to the top of a jack stand, the force is transmitted down the legs of the stand and distributed across a larger area, allowing the stand to support a significant load.
Unlike hydraulic jacks, jack stands are not heavy and nearly impossible to move. They are specifically designed to be light and portable, making them convenient for automotive repairs and other uses.
Therefore, the correct statement is:
C. Jack stands are light compared to the load they can support.
