A roof support frame has various leadings on it. The frictionless pin joint at points A has vertical and horizontal reaction forces. The rollers at point B allow free movement in the horizontal direction and has a vertical reaction.
a/Calculate The total Horizontal reactions in the pin at point A in KN, and the direction as indicated by the arrow in the answer?
b/Describe the vertical reaction at point B in KN?
c/ What is the vertical reaction at point A in KN?
[b]2. Moment = Force * Distance
[b]3. I have attempted this question, but only as if it were a beam, and for the Vertical Force at B i got 5.4KN, and for The Vertical force at A i got 8.6KN. I dont know what to do with the horizontal forces and distances.
