Question

Transcribed Image Text:Scenario. Three specimen of D12 rebar was subjected to a Tensile Test. Using a steel density of
8000Kg/cu.m. With the following result
specimen 1
specimen 2
M=0.895 kg
M=0.89 kg
L=98 cm
L=99 cm
Load at yield strength= 5000 kg
Load at ultimate =8600 kg
Gauge length after test=21.5 cm
Load at yield strength= 5000 kg
Load at ultimate =8600 kg
Gauge length after test=21.6 cm
specimen 3
M=0.897 kg
L=100 cm
Load at yield strength= 5010 kg
Load at ultimate strength=8590 kg
Gauge length after test=21.6 cm
