Consider an infinitely thin flat plate with a 1 m chord at an angle of attack of 10° in a supersonic flow. The pressure and shear stress distributions on the upper and lower surfaces are given by , , , and , respectively, where x is the distance from the leading edge in meters and p and τ are in N/m2 . Calculate the normal and axial forces, lift and drag, moment about the leading edge and moment about the quarter chord point, all per unit span. Also, calculate the locations of the center of pressure.

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)
