A thin elastic wire is placed between rigid supports. A fluid flows past the wire, and it is desired to study the static deflection, \(\delta\), at the center of the wire due to the fluid drag. Assume that

\[
\delta=f(\ell, d, ho, \mu, V, E)
\]

where \(\ell\) is the wire length, \(d\) the wire diameter, \(ho\) the fluid density, \(\mu\) the fluid viscosity, \(V\) the fluid velocity, and \(E\) the modulus of elasticity of the wire material. Develop a suitable set of pi terms for this problem.
