## 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.
