Figure 16. End connection test setup 



The results of these tests are shown in Table IV. It was not possible 



to apply forces greater than 9000 pounds to the ram system because of 



excessive load cell deflection. In summary, the end connections per- 



o 

 formed well on perpendicular surfaces and surfaces with a 10 slope. 



The threaded connections were slightly more rigid than the pinned joints.

*Slippage did not occur but the load cell bent excessively requiring 

 termination of the test at the indicated pressure.
