The box shown in the figure is assembled by gluing two pieces of plastic together at an angle a. The box has a rectangular cross section (a = 100 mm and b = 60 mm). The maximum allowable normal stress for the adhesive is 35 MPa, and the maximum allowable shear stress is 22 MPa. Using a Safety Factor of 1.5, determine: a. Largest allowable load P b. Angle a at this load

the answers are pmax=195kN and the angle is 57.8. can you explain?

The box shown in the figure is assembled by gluing two pieces
of plastic together at an angle a. The box has a rectangular
cross section (a = 100 mm and b = 60 mm).
P
The maximum allowable normal stress for the adhesive is
35 MPa, and the maximum allowable shear stress is 22 MPa.
Using a Safety Factor of 1.5, determine:
a. Largest allowable load P
b. Angle a at this load
Draw all necessary FBD's (these can be incomplete for this
problem), show all work, and put units on your answers.
