A thin elastic wire is placed between rigid supports. A fluid flows past the wire, and itis desired to study the static deflection, 8, at the center of the wire

due to the fluid drag.Assume that 8 = f (l, d, p, µ, V, E) where l is the wire length, d is the wire diameter, p the fluid density, µ the fluid viscosity, Vthe fluid velocity, and E the modulus of elasticity of the wire material. Develop a suitable setof pi terms for this problem.
