Homework Statement
Determine the forces acting on the two rods in the figure. Explain which stresses that act on the rods and the bolts holding the rods to the brackets in point A and C.
Homework Equations
∑Fx = 0 ∑Fy = 0 ∑Fz = 0
∑Mx = 0 ∑My = 0 ∑Mz = 0.
The Attempt at a Solution
∑Fx = 0: Ax – T cos 60 = 0
∑Fy = 0: Ay + sin 60 – 75 = 0
∑Mx = 0: T sin 60  75 = 0
75 = T sin 60
T = 75 / sin 60
T = 86,6 N
Ax = T cos 60
Ax = 86,6 cos 60
Ax = 43,3 N
Ay + sin 60 – 75 = 0
Ay =  sin 60 + 75
Ay = 74,3 N.
I have divided the figure in two: one for rod A B, and one for rod B C. I have then attempted to solve rod A B. But I am not certain how to solve for rod B C. Will it not be basically the same results? Also I am not certain where to explain the normal and shear stress, and the strain.
