Question 2

A non uniform rod AB AB\,AB has length 6 m and mass 18 kg. The rod is supported by two light inextensible strings attached at A A\,A and CCC, where AC=5AC = 5AC=5 m.

Diagram of a non-uniform rod AB of length 6 m supported by two strings at A and C, with AC = 5 m.

a.

Given that the tension in the string at A A\,A is twice the tension in the string at CCC, find the tension in the string at CCC.
