In 1980, alfa romeo introduced the first system to smooth a rough idle caused by ignition and camshaft timing changes.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
