Question 7: Write the solution steps of a numerical problem of the equilibrium.

Answer

The following procedural steps may be taken while solving a numerical problem of equilibrium.

1. Study the problem very carefully and identify all the forces acting on the body.
2. Draw a clear diagram and show all forces acting on the body.
3. Mark all the forces as,, ….. etc.
4. Find all angles θ₁, θ₂, θ₃ … etc.
5. Resolve all forces into their respective x- and y-components.
6. Add all x- and y-components of the identified forces, ∑Fx  and ∑Fy .
7. Apply the conditions for equilibrium,
   • • ∑F_x = 0
     • ∑F_y= 0
     • ∑τ = 0
8. Solve the above equations for the required unknown quantities.
