Explanation:
Value of the cross-sectional area is as follows.
A =![1.5 \times 2.30](/tpl/images/0527/7914/b4afb.png)
= 3.45![in^{2}](/tpl/images/0527/7914/dae19.png)
The given data is as follows.
Allowable stress = 14,500 psi
Shear stress = 7100 psi
Now, we will calculate maximum load from allowable stress as follows.
=![14500 \times 3.45](/tpl/images/0527/7914/9a374.png)
= 50025 lb
Now, maximum load from shear stress is as follows.
=![2 \times 7100 \times 3.45](/tpl/images/0527/7914/b0647.png)
= 48990 lb
Hence,
will be calculated as follows.
= 48990 lb
Thus, we can conclude that the maximum permissible load
is 48990 lb.
