Athin elastic wire is placed between rigid supports. a fluid flows past the wire, and it is desired to study the static deflection,δ, at the center of the wire due to the fluid drag. assume thatδ=f(ℓ,d, rho, u,v, e),whereℓis the wire length, dthe wire diameter, rhothe fluid density,μthe fluid viscosity, vthe fluid velocity, andethe modulus of elasticity of the wire material. develop a suitable set of pi terms for this problem.
