Ben,

 

ASTM D638 and D695 cover the physical properties of acrylic.

The values can be found in Table 2-3.1 of ASME PVHO-1b-2000 also.

 

(psi)

Ultimate tensile 9,000

Compressive yield 15,000

Shear    8,000

Whenever I look for that stuff and ask for help in finding something suitale they always request blueprints that are certified by a professional engineer.  Until I give them that they refuse to give me any info.
