Lami's Theorem

If $\overrightarrow{a}+\overrightarrow{b}+\overrightarrow{c}=0$. The angle between $\overrightarrow{a}$ and $\overrightarrow{b}, \overrightarrow{b}$ and $\overrightarrow{c}$ are $150°$ and $120°$, respectively. Then, the magnitude of vectors $\overrightarrow{a},\overrightarrow{b}$ and $\overrightarrow{c}$ are in ratio of :

Force $\mathrm{F}$ in the given figure equals to 

The three coplanar concurred forces acting at a point $"\mathrm{O}"$ are in equilibrium then the ratio of $\raisebox{1ex}{${\mathrm{T}}_1$}\!\left/ \!\raisebox{-1ex}{${\mathrm{T}}_2$}\right.$ and $\raisebox{1ex}{${\mathrm{T}}_1$}\!\left/ \!\raisebox{-1ex}{${\mathrm{T}}_3$}\right.$ respectively will be

At point $\mathrm{A}$ is in equilibrium under the action of the applied forces, the values of tension. ${\mathrm{T}}_{\mathrm{AC}}=?$

 An iron block of mass 30 kg is hanging from the two supports A and B as shown in the diagram. Determine the tensions in AC ropes.

When three forces acting at a point are in equilibrium, then each force is proportional to the _____ of the angle between the other two forces

Lami's theorem is only applicable for triangles and not for all polygons.

What is Lami's Theorem?

A force of $120 \mathrm{N}$ and a force of $20 \mathrm{N}$ acting simultaneously at a point may produce a resultant force of

An iron sphere weighing $10 \mathrm{N}$ rests in a $V$ shaped smooth trough whose side form an angle of $60°$ as shown in the figure. Then reaction forces are

Cotyledons are also called-

A sphere of mass $m$ is held between two smooth inclined walls. For $\sin 37°=\frac{3}{5}$, the normal reaction of the wall $\left(2\right)$ is equal to:
