Consider a thin, symmetric airfoil at a 6° angle of attack flying at a dynamic pressure of if qw = 6 kpa and with a chord length of 1.5 meters. d) consider replacing this airfoil with a cylinder of diameter 1.5 meters. assuming the flow is inviscid, irrotational and steady, how fast must the cylinder rotate in order to generate the same lift? hint: recall the relationship between the vortex velocity at r = r and the rotation speed.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

On a average work day more than work place firs are reorted

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
