The homoegeneous wire ABCD is bent as shown and is supported by a pin at B. Knowing that l=8, determine the angle theta for which portion BC of the wire is horizontal.(adsbygoogle = window.adsbygoogle || []).push({});

Below is the free body diagram with the forces exerted by the pin indicated by the two arrows on the wire.

How do I approach this problem?

The first part of the wire is a semi-circle with radius 6 and second part a horizontal line with length 6, and the third part a diagonal line iwth length 6.
