Both bars have the same cross-sectional area 1 = 2 = with allowable tensile and compressive strengths of 20 and 15 respectively. As well, theta1 = theta2 = theta, and the dimension is constant. Determine the optimal design of this truss ( and theta) to obtain the minimum volume while satisfying the given stress constraints (this is the one we did in class). Use trial and error with an Excel spreadsheet and on your excel spreadsheet clearly indicate your design choice.

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer,e = 5 × 105?
