The rectangular bar is connected to the support bracket with a 19-mm-diameter pin. The bar width is w = 75 mm and the bar thickness is 20 mm. Each side of the bracket has the same dimensions as the bar. The average shear stress in the pin cannot exceed 120 MPa, the bearing stress in the bar cannot exceed 150 MPa, and the bearing stress in the bracket cannot exceed 150 MPa. Determine the maximum value of Pmax that can be supported by the structure.

Question
The rectangular
bar is connected to the
support bracket with a 19-mm-diameter pin.
The bar width is w = 75 mm and the bar
thickness is 20 mm. Each side of the bracket
has the same dimensions as the bar. The
average shear stress in the pin cannot exceed
120 MPa, the bearing stress in the bar cannot
exceed 150 MPa, and the bearing stress in the
bracket cannot exceed 150 MPa. Determine
the maximum value of Pmax that can be
supported by the structure.
Answer: Pmax=
