	$u s i n g m y o w n m e t h o d :$ $l e n g t h o f s t r i n g$ $2 y_{A} + 2 y_{B} + y_{C} = L = c o n s t a n t$ $\Rightarrow 2 \frac{{d y}_{A}}{d t} + 2 \frac{{d y}_{B}}{d t} + \frac{{d y}_{C}}{d t} = 0$ $\Rightarrow 2 V_{A} + 2 V_{B} + V_{C} = 0$ $\Rightarrow 2 a_{A} + 2 a_{B} + a_{C} = 0$ $+ d i r e c t i o n i s d o w n w a r d s (↓)$ $e x a m p l e :$ $V_{A} = - 3 (↑)$ $V_{B} = 5 (↓)$ $\Rightarrow 2 (- 3) + 2 \times 5 + V_{C} = 0$ $\Rightarrow V_{C} = - 4 (↑)$
