What is meant by equilibrium of a bent rod under a load?

Dear Student,

Please find below the solution to the asked query:

For any body or system, the meaning of equilibrium means,

The net force on the body is zero.

$$\begin{gathered} \underset{i=1}{\overset{n}{\sum \overrightarrow{F_i}}}=0 \\ \Rightarrow \Sigma \overrightarrow{F_x}=0; \Sigma \overrightarrow{F_y}=0 and \Sigma \overrightarrow{F_z}=0 \end{gathered}$$

The net torque on the body is zero.

$$\begin{gathered} \underset{i=1}{\overset{n}{\sum \overrightarrow{{\tau }_i}}}=0 \\ \Rightarrow \Sigma \overrightarrow{{\tau }_x}=0; \Sigma \overrightarrow{{\tau }_y}=0 and \Sigma \overrightarrow{{\tau }_z}=0 \end{gathered}$$

So, if the bent rod is under equilibrium means, net force and net torque on the rod is zero.
