1.Determine the components of displacement at 1. Take E = 200 GPa, I = 250(10^6) mm^4, A = 12(10^3) mm^2 for each member.
2.Using Buckingham-Pi method, derive a relationship to evaluate the discharge, Q, over a rectangular notch as a function of the width of notch, b, acceleration due to gravity, g, fluid density, p, dynamic viscosity, µ, depth of flow, h, and surface tension (force per unit length), r. Choose repeating variables in the following order: b, g, p,µ,h, r , Q.
