Q1. Air at 20degrees Celsius with upstream of velocity u= 2.5m/s, flow parallel to a flat plate with length L=50cm and breath b=3m. Density = 1.2kg/m^2, v= 1.5×10^-5 m^2 /a
i. Find the drag D on one side of the plate.
ii. The boundary thickness at the trailing edge.
Q2. Suppose that the tip deflection s of a cantilever beam depends on the factors such as the tip load p, beam length L, area moment of inertia I, and material modulus of elasticity E, expressed as S= f( P, L, I, E ). Rewrite this function in dimensionless form.
