A particle P is acted by three coplanar forces as shown in the figure.Find the force needed to prevent the particle P from moving. (take$$ $$3$$ $$=$$ $$1.7)

Infinity Learn · Accepted Answer

Let applied force is $$F4$$ $$=$$ Fx $$i^+Fyj^To$$ prevent the particle P from moving, net force on the particle will be zero.∴    ∑ Fx $$=$$ $$0or$$ ∑ Fx $$=Fx+150+200cos300$$ $$=$$ $$0$$∴ Fx $$=$$ $$-150-1003$$ $$=$$ $$-(150+170)$$ $$=$$ $$-320$$ N and ∑ Fy $$=$$ $$0or$$ $$200$$ $$sin300$$ $$-$$ $$100+Fy$$  $$=$$ $$0$$  ∴  Fx $$=$$ $$0It$$ means $$F4$$ is direction opposite to $$F1$$.
