Physics - Rotation Question with Solution | TestHub

A uniform boom of mass 120 kg is at angle $\varphi =60^{\circ }$ from horizontal. It is supported by a cable at an angle $30^{\circ }$ from horizontal. The boom is pivoted at the bottom and object of mass $\mathrm{m}=200\mathrm{kg}$ hangs from it's top. If Tension in the support cable is T , find $\frac{3\mathrm{T}}{13\mathrm{g}}$ (in SI unit)
