Hello everyone, For this equation, I have found Ay as 0.677kN by using Ma = 1.5kN(7m)-Ay(15.5m). To find Cy, would I be using the sum of forces to find the answer? For example Fy = Ay - F2 - F1sin55 + Cy = 0 This would then get Cy answer as 2.05kN

That gives me a y force of -4kN. This does not give me the answer to Tb. Do I now use the Z and Y axis to figure out my answer since Fx = 0

I see it now. I was looking at it the wrong way. Completely overlooked the direction in which y was going so it should be a negative. As the X goes along both the positive x-axis and negative x-axis the sum will equal to zero. So the resultant should be -8sin30y?

My bad. Fr should be 5.65. (4cos30)^2+(4sin30)^2 and then root the answer.

Sorry for the late reply. Would Fr not be the sum of all forces which is 4cos30+4sin30+4cos30+4sin30 = 11

The component has a x y z, does that not make it 3d with there being 3 axis. Anyways, the question simply said .

The boom is supported by a ball-and-socket joint at AA and a guy wire at BB Hey guys, I am stuck with this question in find the Tension in B and the moments around A. I have done plenty of 2d Tension questions but not a 3D one.
