Only half of the lugs are given in Fig. 13. Lug with mark U9 has three holes, U10 has five holes, and U11 has seven holes. It can be seen that the lug marked U11 has the lowest equivalent stress value 122MPa   , as well as lowest value of strain max f =0,0245mm . Display of the deformed models with maximum displacement and equivalent stress values are given for each lug in the Fig. 13.

U9 f max = 0,294 mm σ emax = 132 MPa

U10 f max = 0,246 mm σ emax = 126 MPa
