A wing has a planform area S of 100 ft^2 and a total span b of 20 feet. The same symmetric airfoil is used all along the span. The wing is untwisted, untapered, and swept back at 30 degrees. The freestream Mach number is 0.5. Sketch the planform you would use to analyze this wing in a low speed (incompressible) wind tunnel. Show all dimensions (root, tip, semi-span), and the leading edge sweep.

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
