Question

Applying equilibrium conditions, $\Sigma F_{x}=0 \quad \Rightarrow F_{1}+1 \sin 45^{\circ}-2 \sin 45^{\circ}=0$

or $F_{1}=2 \sin 45^{\circ}-1 \sin 45

Vedclass · Accepted Answer

$\frac{1}{\sqrt 2}N,\frac{3}{\sqrt 2}N$

Vedclass · Answer

Applying equilibrium conditions, $\Sigma F_{x}=0 \quad \Rightarrow F_{1}+1 \sin 45^{\circ}-2 \sin 45^{\circ}=0$

or $F_{1}=2 \sin 45^{\circ}-1 \sin 45^{\circ}$

$=1 \sin 45^{\circ}=\frac{1}{\sqrt{2}} \mathrm{N}$

$\Sigma F_{\mathrm{y}}=0$

$\Rightarrow \mathrm{F}_{2}=1 \cos 45^{\circ}+2 \cos 45^{\circ} \Rightarrow \mathrm{F}_{2}=\frac{3}{\sqrt{2}} \mathrm{N}$

There are four forces acting at a point $P$ produced by strings as shown in figure, point $P$ is at rest. The forces $F_1$ and $F_2$ are respectively:-
