NORMAL STRAIN UNDER AXIAL LOADING
Let us consider a rod BC, of length L and uniform
cross-sectional area A, which is
suspended from B . If we apply a load P to end C,
the rod elongates.
Plotting the magnitude P of the load against the
deformation del

Question 1
Two solid cylindrical rods AB and BC are welded together at B and loaded as shown
in Figure 1. Determine the average normal stress at the midsection of (a) rod AB, (b)
rod BC.
Question 2
Each of the four vertical
