352 JAMESON ON TESTING THE STRENGTH OF MATERIALS. [SeIectcd (Students` Paper No. 400.) " TestingtheStrength of Materials." By ALEXANDER JAMESON, Stud. Inst. C.E. HOPE M.Sc., THE simplest method of testing the strength of a material would be to fasten one end of a specimen to a support hang and weights 011 the other end till it broke, having previously marked a known length on the bar so that its elongation until fracture might be measured. This method is satisfactory if the specimens are, as in the case of wire, small, or the material weak, and the loads required, therefore, small enough t o handle with ease, provided the weights are added gently so that no shock occurs...
