3 WITNESS WOYTCWICH: Yes.
4 I den 't have a calculater tc ccnvert 5 that t o kilevatts f or you .
6 C Tha t is all right.
7 I refer you te 34.3.2 of the rules, 1583 8 rules. What is meant by the first phrase cf that first 9 sentence in the paragraph, that the design equatices to don 't take inte consideration the pcssibility of 11 dancer cus tersional vibraticn stresses ?
12 Which design equations dces the phrase 13 ref er tc?
14 WITNESS GIUEEFA: Fcr example, the tatic 15 crankshaf t dia me te r f o rmula , 3 4.17.1. That would 16 assume that the stress values are icwer than these 17 a p p ea r ing in the later table or the formulas in the 18 1984 rules.
19 So that you s c ul d--y~c u sculd a;;reve the 20 d esign with tha t c e nsid era tion . If the stress values 21 a re highe r, we have tc cc inte a further detail in ccr l 22 review of the design.

T C Did the existence of these values as 8 being higher than this allesable li it er limits have 9 any ef-f ect on your prict calculations as to whether tne 10 de sig n equations had been zet fcr this crankshaft?

I 116 1 WITNESS GIUFERA: Well, it reans that we 2 vent back and did some additional calculations. We 3 reviewed their strain-cauge measurements as well at 4 torsiograph measurements and looked at the service 5 dcctme ctaticn they had give r tc us, w hich is available 6 here.
7 We used those in conjunction with our 8 cwn ch eck calculatic=s tc determine that it was 9 accept able f or a mar--f or a ncn-marine calculatien.

4 UITNESS WCYTCWICH: H a n d w ri t re n '. We 5 ccvere d this morning as far as sheet Fc. 3 cf six. I 6 assrae ycu will want tc come back later to the T remainder of that.
8 Then, after the handwritten calcciaticn 9 that is marked " Sheet 6 of 6," there a re twe pages to which censist er three pages which censist cf copies of 11 calcul a te r grin tou ts . These were the safety facter 12 calculaticns which we made according to our modified .
13 version cf the CIP.AC draft rethed.
14 Then, following that--
15 C If I can sto; ycu there , what is "SI"?
16 A System Internaticnal, international 17 sys tem cf units.
18 Ec11 cuing that, there shculd be scre--s 19 sheet indicating saf ety f acters. We calculated the 20 safety facters in several ways. We began with the 21 f a tiqu e stre ss, which se chtained from th e calculater 22 printo ut marked " Sheet 3 of 3" by AJD/?.TW.
ALDfR$ON REPORTING COMPANY, INC.

118 1 The re is a--the fc ur th printout line up 2 from the bottom gives the stress in Newton 's per square 3 millin e ter, con verted te psi.
4 Q What is that figure?
5 WITNESS WOITCEICH: 29,c40 psi.
6 Q Helating to what?
7 WIT 5ESS WCYTCEICH: That relates te the 8 eq uiv a le nt ccnhined alternating stres: ty Vcn Ness' 9 thecry.
10 Going back tc the handw ritten sheet , we 11 cc m gar e d tha t stress against each of the three f atique 12 streng th valuer , which we had tc consider. Cne was the 13 result cf the theoretical fctmula prcpcsed by CIMAC.
14 That indicated a safety facter cf l
15 1.105. Then we compared it tc the fatique strength 16 value which TDI Indicated has derived frcr tests er the 9 17 failed crankshaft, withcut shot geening.
18 And the safety facter was fcund tc te 19 1.2C9.
20 Then we concluded the 20 percent extra 21 streng th which they claimed for shot peening, and that 1
22 inc rea sed safety f actor to 1.57.

11 WITNESS WOYTCWICH: I have discussed the 12 fir st few lines of that. Ncw we are lecking at the 13 next headiac dcwn, "Certined S.F. Gccdman .ethed." M 1' Eased on the ultimate tensile strencth 15 of the fcccings and on the steady and alternating 16 loads, we calculated ccmhined safety facters, ence by 17 the Cocdman method, which uses reciprocal addition of 18 the steady and alternating safety facters, ence by the 19 eliptical theory f cr ccmbined leadings , which uses the M square s of each cf these safety facters.

4- f actors are marginal, but when we included the 20 5 pe rcen t credit for shot peering, they went well ever 6 the de sired minimum.
7 I might aise add here that in this case, 8 these numbers were determined at th e 110 percent lead 9 ra t ing . we didn't go back and recalculate when we 10 d e cide d ret tc address that question in our letter, 11 because we felt since it was acceptable , f er the me s t 12 part, under these circumstances, that we wculd not gc 13 back a nd recaleclate it , f er the maximum centinucus 14 ra ting .
