How strong is duct tape?

Original duct tape, which is suitable for general use, has a tensile strength of 19 lbs. per inch; other variations of duct tape are just as sturdy, and withstand high temperatures and forces. Duct tape sees use in many disciplines, including the military, space and car racing. It can withstand winds of up to 100 miles per hour and has helped repair space ships, race cars and other equipment because of its durability.

The strength of duct tape varies depending on quantity used. The Discovery Channel put duct tape to the test performing several tasks, including serving as suspension systems for cars, constructing watercraft and building canoe paddles. A hammock made of duct tape even holds the weight of an adult male.
