Answer to Question #310968 in Mechanics | Relativity for Lili

Question

So how would you calculate the force of F needed to keep the engine stationary by first resolving the forces into their horizontal and vertical components.

Answer 1

Answer

If a force is at $\theta$ angle from +x axis then it's horizontal and vertical components are

$F_H=F\cos\theta$

$F_v=F\sin\theta$
