Equilibrium of particle under coplanar forces

A question is this type if and only if it involves a particle in equilibrium under multiple coplanar forces (typically 3-4 forces) where you must find unknown magnitudes or angles by resolving forces in two perpendicular directions.

A cylindrical object with mass 8 kg rests on two cylindrical bars of equal radius. The lines connecting the centre of each of the bars to the centre of the object make an angle of \(40°\) to the vertical. \includegraphics{figure_2}
  1. Draw a diagram showing all the forces acting on the object. Describe each of the forces using words. [2]
  2. Calculate the magnitude of the force on each of the bars due to the cylindrical object. [7]
