A wing has a lift-curve slope of 5.2 per radian, and the product of eAR is 8. Given that a second wing has an effective aspect ratio (eAR) of 6.0 and the same airfoil as the first wing, how fast must this second wing travel in order to lift 3000 lbs. when it is at an angle of attack of 6.0 degrees. The area of the second wing is 300 ft2, and the angle of zero lift angle is -1.0 degree. Assume that both wings are operating at standard sea-level conditions.

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

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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
