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¦.
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many pe â¦ ople would call and estimate.
