How many types of tension should be considered when rigging for a job?

When rigging, you must consider three kinds of tension the system may experience: static tension from the weight of the load when everything is steady; dynamic tension that arises when the load is being moved, accelerated, or decelerated; and shock or impact tension from sudden changes, jerks, or abrupt stops. Each type can produce higher forces than the others, so the equipment and anchors need to be rated for the worst-case combination of these tensions with appropriate safety factors. If any one type is overlooked, you risk overloading gear and creating a hazardous situation.
