$2\mathrm{.}44$ Two cables are tied together at $C$ and are loaded as shown.

Knowing that $=20,$ determine the tension $($a$)$ in cable $AC,(b)$ in cable

$BC.$

$2\mathrm{.}57$ Two cables tied together at $C$ are loaded as shown. Knowing that

the maximum allowable tension in each cable is $$00N,$ determine $($a$)$ the

magnitude of the largest force P which may be applied at $C,(b)$ the corre$-$
