QUESTION:

Three forces, each of magnitude P = 4 kN, are applied to the structure shown. Determine the cross-sectional area of the uniform portion of rod BE for which the normal stress in that portion is +100 MPa.

ANSWER:

Step 1 of 6

In the given problem we have to find the cross sectional area of member BE. We are provided with the normal stress acting in the member BE .

We will first consider the equilibrium of sections CD and separately to calculate the axial force in member BE. From the force thus found, we will calculate the required cross-sectional area.
