Classical Mechanics Level 4

Given a toy with \(2N\) bars with mass each bar m kg angle between two adjacent bars is \(\theta = 90^\circ\).

Find the force \(F\) applied for equilibrium if \(m=1\text{ kg},N=10,g=9.8\).

the toy is fixed at point A.

Assume the surface is smooth.

A single bar is highlighted in the pic.
