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¦.
A simple way to determine the ideal mechanical advantage to a pulley system is to count the number of lengths of rope between pulleys that support the load. In Figure 1(a), only one segment of rope supports the load.Th erefore, the mechanical advantage is 1.n this Investigation, you will be testing factors that might infl uence the actual mechanical advantage of pulley systems. A single fi xed pulley, like the one in Figure 1(a), has an ideal mechanical advantage of 1 since the eff ort force (120 N) is equal to the load force (120 N).
