| X. 3513 EFC/T18.12.22. X. 3513 - COMPARATIVE STRENGTH TESTS OF THREE MOULDING MATERIALS:- 'BAKELITE', 'ELO', & 'MOULDENSITE' In these tests the specimens were rods .600" square section. These were successively clamped horizontally at one end and loaded at the other end at such a distance as to provide a free length of overhang of 6", until fracture occurred. The loads necessary in the three cases were:- Bakelite 53 lbs. 14 ozs. Elo 54 " 10 " Mouldensite 59 lbs. 6 ozs. These figures correspond to breaking stresses of 8980 lbs/sq." 9105 lbs/sq" and 9897 lbs/sq" respectively. EFC | ||
