bracket with a $11-$mm$-$diameter pin. The bar width

is $w=75mm$ and the bar thickness is $10$ mm $.$ Each

side of the bracket has the same dimensions as the

bar. The average shear stress in the pin cannot

exceed $135$ MPa $,$ the bearing stress in the bar

cannot exceed $150$ MPa $,$ and the bearing stress in

the bracket cannot exceed $120$ MPa $.$ Determine

the maximum value of $P_{\text{m}\text{a}\text{x}}$ that can be supported

by the structure.

Answer: $P_{\text{m}\text{a}\text{x}}=$
