The maximum load/force a device/wire/pulley, etc. can sustain. Explanation: The matter can be understood as follows: You tie a rope to a branch of a tree and allow its one end hang in the air. To this free end, you go on adding weight/force, allowing the weight/force hang freely. A point will reach when either the branch of the tree will break or the rope will snap. In the first case, just before the branch breaks, the maximum load/force borne by the branch is the tensile strength of the branch; in the event of rope-snapping, the maximum load/force borne by the rope is its tensile strength. |
