When an object rests on an incline that makes an angle θ with the horizontal, the force of gravity acting on the object is divided into two components: a force acting perpendicular to the plane, w⊥, and a force acting parallel to the plane,$\textbf{w}_{\parallel}$.
The magnitude of the component of the weight parallel to the slope is ${w}_{\parallel }={w} \sin({ 25}^{\circ}) = mg\sin ({ 25}^{\circ})$, and the magnitude of the component of the weight perpendicular to the slope is ${w}_{\perp}={w}\cos({25}^{\circ}) = mg\cos({25}^{\circ})$. (Forces perpendicular to the slope add to zero, since there is no acceleration in that direction.) Physically, the boundary-layer development on a rotating cylinder in an axial stream is equivalent to that on a flat plate with the fluid subjected t o outward normal forces. { bidder: 'ix', params: { siteId: '195465', size: [300, 250] }},
