Question

Determine the components of reaction at A and B
1) Determine the vertical component of reaction at B. By=?? Bx=0

2) Determine the horizontal component of reaction at A. Ax=??

3)Determine the vertical component of reaction at A. Ay=??

I need a final answer with a slolution please

Explanation / Answer

Let R = normal reaction at peg B. Taking moments of forces about A, R * (0.40) = 600 * (0.80) cos30° ... [angle between AC and normal to the direction of F = 30°] => R = 1039 N. Let Rx and Ry be the horizontal (to the right) and vertical (upwards) components of reaction at pin A. Balancing horizontal components of all the forces, Rx = Rcos60° + Fcos30° = 1039 * cos60° - 600 * cos30° = - 0.115 N [Negative sign indicates that the horizontal reaction at A is to the left.] Balancing vertical components of all the forces, Ry = Fsin30° - Rsin60° = 600 * sin30° - 1039 * sin60° = - 599.8 N
