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.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
