# Tripod

Consider a tripod consisting of three uniform bars (legs) of length $$a$$ and mass $$m=0.8~\mbox{kg}$$, freely jointed at point A. The middle points of the legs of the tripod are joined by 3 massless strings of length $$b$$. The tripod rests on a smooth surface while supporting a camera of mass $$M=1~\mbox{kg}$$. If $$\frac{a}{b}=4$$ determine the tensions $$T$$ in Newtons in the strings. Assume $$g=9.8~\text{m}/\text{s}^2$$.
