Figure 1 shows a beam \(A B\) with weight 24 N and length 6 m .
The beam is suspended by two light vertical ropes. The ropes are attached to the points \(C\) and \(D\) on the beam where \(A C = x\) metres and \(C D = 2 \mathrm {~m}\).
The tension in the rope attached to the beam at \(C\) is double the tension in the rope attached to the beam at \(D\).
The beam is modelled as a uniform rod, resting horizontally in equilibrium.
Find
- the tension in the rope attached to the beam at \(D\).
- the value of \(x\).
