Question 5

A non-uniform beam $LM\,$ has length 10 m and mass 24 kg. The beam is supported in a horizontal position by two light vertical cables attached at $L\,$ and $N$ , where $L N = 8$ m.

Given that the tension in the cable at $L\,$ is five times the tension in the cable at $N$ .

Find the tension in the cable at $N$ .

[2]

Find the distance of the beam's centre of mass from $L$ .
