The symmetrical scissors truss shown below is supported at point A and D. The support at D is a rocker bearing and does not produce a horizontal reaction. A, B, C, D, E & F are pin joints. The members of the truss are not joined to each other where they cross. At A, the angle between AB and AE is 45° and the angle between AC and AE is 26.57°. The load at E is P18 kN and the load at F is P19 kN.
The magnitude of the reaction force at D in kN rounded to 1 DP is
Ans:
The load at F is now changed so that the vertical reaction at A is P20 kN. The Load at E remains the same.
