Shear Resistance)은 마찰력(Friction)과 점착력(Cohesion) 두 성분으로 이루어진다는 사실을 밝혔다.

as the force per unit area. Thus, ropes of varying
length that are otherwise identical require the same force to reach the breaking point. The actual distance the rope
stretches before breaking is greater for a longer rope—more work, and thus more energy, is required to break a
longer rope.
