Ecuaciones <strong>de</strong> <strong>Equilibrio</strong><br />
∑ M x =0 ;T C (2m)−981 N (1m )+B Z (2m)=0<br />
∑ M y =0 ;<br />
300 N (1 .5m )+981 N (1 .5m )−B z<br />
(3m )− A z<br />
(3m )−200 N . m=0<br />
• La componentes <strong>de</strong> la fuerza en B se pue<strong>de</strong>n eliminar<br />
si se usan los ejes x’, y’, z’<br />
∑ M x'<br />
=0 ; 981 N (1m )+300 N (2m)− A z<br />
(2m)=0<br />
∑ M y' =0 ;<br />
−300 N (1. 5m )−981 N (1 . 5m)200 N . m+T C<br />
