The above figure shows the three coplaner forces P, Q and R acting at a point O. If these forces are in equilibrium, then
|
A.
\(\frac { P } { sin\beta } = \frac { Q } { sin\alpha } = \frac { R } { sin\gamma}\) |
|
B.
\(\frac { P } { sin\alpha } = \frac { Q } { sin\beta } = \frac { R } { sin\gamma}\) |
|
C.
\(\frac { P } { sin\gamma} = \frac { Q } { sin\alpha } = \frac { R } { sin\beta}\) |
|
D.
\(\frac { P } { sin\alpha } = \frac { Q } { sin\gamma} = \frac { R } { sin\beta}\) |
