Abstract – Banana Friction: In this study, we examine the myth that a person can step on a banana peel, slip and fall. On the foundation that the static friction force is an essential parameter of whether the person will slip, we build up an experiment for the detection of the frictional force between a banana peel and two different surfaces (tile and wooden floor). Using a theoretical basis for gait analysis and force development during a gait cycle, we establish a criterion that must be met, in order for slipping to be probable. This criterion indicates that the static coefficient of friction (μ_s) between the banana peel and the ground must be less than the ratio of the horizontal and vertical forces in the gait cycle (Q), if the person is intended to slip. Using our experimental setup, and the generated results, we perceive that slipping is a possibility on both types of surfaces, but only if the ideal conditions are met. The person is required to hit the peel perfectly, at the right time in the gait cycle (loading response), and so it is possible to slip on a banana peel, but this risk is very small.
