Compared to mild steel, cast iron has
(i) High compressive strength
(ii) High tensile strength
(iii) Low compressive strength
(iv) Low tensile strength
A. (i) and (ii)
B. (ii) and (iii)
C. (iii) and (iv)
D. (i) and (iv)
Answer: Option D
This Question Belongs to Civil Engineering >> Building Materials
The ultimate compressive strength of mild steel varies from 800 to 1200 n/mm2. The ultimate compressive strength of the cast-iron is 600 n/mm2 and The ultimate tensile strength of mild steel varies from 600 to 800 N/mm2. Cast-Iron. The ultimate tensile strength of Cast-Iron is 150 N/mm2.
so correct answer is Option C.
