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.

grav potential energy

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
