Because the natural world is full of hydrophobic and hydrophilic surfaces, the basics of the phenomenon have been known by scientists for at least two centuries. For example, the lotus leaf is a well-known example of a hydrophobic material, protecting the water-dwelling plant from becoming waterlogged.
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.Value of mechanical advantage is load(L)/Effort(E). â¦.
Shimano (Servo-Wave Â®) and Odyssey both make mountain-bike type levers with a variable mechanical advantage that increases as the lever is pulled. 1  The individual cantilever's mechanical advantage is the ratio between the pivot-cable distance (PC) and the pivot-shoe distance (PS) .
