Mechanisms subjected very rarely
to the maximum load and normally
to light loads
Mechanisms
frequently to the maximum load but
normally to rather moderate loads
Mechanisms subjected frequently to
the maximum load and normally to
loads of heavy magnitude
Mechanisms subjected regularly to
the maximum load
