Final answer:
A jack stand has a small chance of failure due to its sturdy construction, low weight, and mechanical design.
Step-by-step explanation:
The chance of a jack stand failure is very small because it is mechanical and sturdily constructed. Jack stands are designed to handle heavy loads and are made from strong materials such as steel. They have multiple adjustable height positions to provide stability and support.
Additionally, the weight of the axle stand is relatively low compared to the weight it can handle. This means that the load on the jack stand is well within its capacity, reducing the likelihood of failure.
