Question
What is meant by resolving a force into rectangular components? Resolve a force of 10N into two components, if it acts at an angle 30° with the horizontal.
✓
Answer
Let F be the force at 30° to horizontal.
The horizontal component is,
$\text{F}\cos30^\circ=\frac{\sqrt{3}\text{F}}{2}$
The vertical component is, $\text{F}\sin30^\circ=\frac{\text{F}}{2}$
The horizontal component is,
$\text{F}\cos30^\circ=\frac{\sqrt{3}\text{F}}{2}$
The vertical component is, $\text{F}\sin30^\circ=\frac{\text{F}}{2}$
