The drag on an airplane wing in flight is known to be a function of the density of air (), the viscosity of air(), the free-stream velocity (U), a characteristic dimension of the wing (s), and the shear stress on the surface of the wing (s). Show that the dimensionless drag, sU2, can be expressed as a function of the Reynolds number, Us.
The power P required to turn a ship will depend on its velocity V , its length L, its width B, the water density ρ and viscosity µ, the rate of turning ω, and the acceleration due to gravity g.

" Centroids " from the Book Engineering Mechanics Statics and Dynamics by Ferdinand Singer. I think the solution is like the one in the second picture, i just cannot get the right answer in the answer key given please help me thankyou! I think the one that is in the answer key was the Xbar (X̅) and Ybar ( ȳ ).
Make a graph of x versus t for the ball. Because you havedata only at certain instants of time, your graph should consist of dots that are not connected together.
Given: Mass = M, Radius = R, Moment of Inertia = I, Distance = H, Gravity = g, Initial timing = 0 Unknown = How long will the [delta t] process take?
