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¦.
Students will: 1  calculate mechanical advantage of levers of their own construction by measuring effort and resistance distances and by measuring force. 2  generate their own procedure for collecting experimental data.
