Sol.: Free body diagram is as shown in the figure given to us

∑H = 0

RAH + 8 cos45° - Rsin30° = 0

0.5 RB - RAH = 5.66                                                                                                                                 ...(i)

∑V = 0

RAV  -10 - 8 cos45° - 10 + RB cos30° = 0

RAV  + 0.866 RB = 25.66                                                                                                                            ...(ii)

Taking moment about A:

∑MA = 10 × 2 + 8 cos45° × 4 + 10 × 7 - RB cos30° × 8= 0

RB = 16.3KN                                                                  .......ANS

From the equation (ii)

RAV = 11.5KN                                                                  .......ANS

From the equation (1)

RAH = 2.5KN       .......ANS
