Claim 10:
11. A method of testing the collapse strength of a tubular member, comprising:
providing a tubular member having a circumference;
forming a loop of a first flexible cable around said tubular member;
connecting said loop to a force generator for exerting an upward force on said loop;
providing a length of a second flexible cable having first and second ends;
looping said second flexible cable over said tubular member;
attaching said first end of said second flexible cable to a first anchor positioned below said tubular member;
attaching said second end of said second flexible cable to a second anchor positioned below said tubular member;
applying an upward force on said loop to place said loop and said second flexible cable in a predetermined amount of tension, whereby said loop and said second flexible cable cooperate to apply a generally uniform radially inwardly directed force around the circumference of said tubular member.
