	$a s s u m e w i s ↓ .$ $W = w \times 5 = 2.5 \times 5 = 12.5 N$ $H A = 0$ $Σ M_{B} = 0 :$ $V A \times 10 + 7 \times 9 - 12.5 \times 5.5 + 8 \times 2 = 0$ $\Rightarrow V A = - 1.025 N$ $Σ M_{A} = 0 :$ $V B \times 10 + 7 \times 1 - 12.5 \times 4.5 + 8 \times 8$ $\Rightarrow V B = - 1.475 N$ $c o n t r o l l :$ $V A + V B = - 1.025 - 1.475 = - 2.5 N$ $7 - 12.5 + 8 = 2.5 N ✓$
