When distributing shear load for an item that pulls away frequently, how much larger should the backing tape surface area be in the direction of the expected pull?
Answer
Up to four times the surface area of the Velcro strip.
For significant or dynamic loads, the surface area of the backing tape in the direction of the pull force should be substantially larger—up to four times the surface area of the Velcro—to distribute the resulting stress effectively across the mounting surface.
