D. Corrected Area(cm2)
1. CA =Area
(1−ɛ )
= 36,2984
(1−0,034)= 37,5759 cm2 = 0,0038 m2
2. CA =Area
(1−ɛ )
= 36,2984
(1−0,035)= 37,6149 cm2 = 0,0038 m2
3. CA =Area
(1−ɛ )
= 36,2984
(1−0,037)= 37,6930 cm2 = 0,0038 m2
4. CA =Area
(1−ɛ )
= 36,2984
(1−0,039)= 37,7714 cm2 = 0,0038 m2
5. CA =Area
(1−ɛ )
= 36,2984
(1−0,041)= 37,8502 cm2 = 0,0038 m2
6. CA =Area
(1−ɛ )
= 36,2984
(1−0,043)= 37,9293 cm2 = 0,0038 m2
7. CA =Area

(1−0,045)= 38,0087 cm2 = 0,0038 m2
E. Reading (KN) & Load (P) (kg)
1. 24 kN P = 24 kN × 101,97
= 2447,32 kg
2. 26 kNP = 26 kN × 101,97
= 2651,26 kg
3. 40 kN P = 40 kN × 101,97
= 4078,86 kg
4. 96 kNP = 96 kN × 101,97
= 9789,27 kg
5. 100 kNP = 100 kN × 101,97
= 10197,16 kg
6. 114 kNP = 114 kN × 101,97
= 11624,76 kg
7. 134 kNP = 134 kN × 101,97
= 13664,19 kg
F. Stress [ P/A (kN/m2)]
1. Stress = PA
= 2447,320,0038
= 64403,158 kN/m2
2. Stress = PA
= 2651,260,0038
= 697700 kN/m2
3. Stress = PA
= 4078,860,0038
= 1073384,211 kN/m2
4. Stress = PA
= 9789,270,0038
= 2576123,684 kN/m2
5. Stress = PA
