Figure 1
A uniform rod of length 72a is cut into pieces. The pieces are used to make two rigid
squares, ABCD and PQRS, with sides of length 10a and 8a respectively. The two
squares are joined to form the rigid framework shown in Figure 1.
The squares both lie in the same plane with the rod AB parallel to the rod PQ.
Given that
• AD cuts PQ in the ratio 3 : 5
• DC cuts QR in the ratio 5 : 3
(a) explain why the centre of mass of square ABCD is at Q.

(b) Find the distance of the centre of mass of the framework from B.
