Question

jeff placed a load of 500 n on a spring balance that was programmed to carry a maximum load of 400 n. after he removed the 500 n load, the pointer did not return to the zero mark on the scale. why? the spring balance was cheap. the pointer was not properly adjusted. the elastic limit of the spring material had been exceeded. the 500 n load was removed.

Explanation:

When a load of 500 N is placed on a spring - balance designed for a maximum load of 400 N, the elastic limit of the spring material is exceeded. When the elastic limit is exceeded, the spring does not return to its original shape and size even after the load is removed.

Answer:

The elastic limit of the spring material had been exceeded.
