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¦.
In a compound machine, how could the ideal mechanical advantage be calculated? A. Combine the ideal mechanical advantages of each simple machine part of the compound machine. B. Divide the work output by the work input of the whole machine. C. Combine the ideal mechanical advantage of the first and last simple machine in the compound machine. D. Calculate the ideal mechanical advantage of the first simple machine within the compound machine.
