Question 44

A non uniform rod AB AB\,AB has length 5 m and mass 12 kg. The rod is supported by two light inextensible strings attached at A A\,A and CCC, where AC=4AC = 4AC=4 m.

Diagram of a non-uniform rod AB of length 5 m supported by two strings at A and C, where AC = 4 m.

a.

Given that the distance of the rod's centre of mass from A A\,A is 43\displaystyle \frac{4}{3}34​ m, find the tension in the string at CCC.

[2]
b.

Find the tension in the string at A A\,A and hence find the ratio of the tension at A A\,A to the tension at CCC.
