Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>View the entire bridge as the system, and find the torque about a pivot chosen to eliminate the torque from one of the unknowns
</span>Find the sum of the torques ∑ τ Q about the right pier Q of the bridge. Remember that counterclockwise torque is positive
∑τQ - 2MgL− 3FpL

<span>The sum of the torques is zero
</span>
FP = 2/3 Mg

F = m*a

30 N = (ma + mb) * a

30 = 5*a

a = 6 m/s ^2

F de B em A

30 - F de B,A = ma * a

30 - F de B em A = 3 * 6

30 - 18 = F de B em A

12 = F de B em A


Resposta: 6 m/s^2 e 12N
