160 N/mm2
260 N/mm2
420 N/mm2
520 N/mm2
Answer is Right!
Answer is Wrong!
The correct answer is C. 420 N/mm2.
The ultimate tensile strength (UTS) of a material is the maximum stress
that a material can withstand before it fails. It is usually measured in megapascals (MPa) or newtons per square millimeter (N/mm2).Structural mild steel is a type of steel that is used in construction and other applications where strength is important. It has an UTS of about 420 N/mm2.
Option A is incorrect because the UTS of structural mild steel is not 160 N/mm2.
Option B is incorrect because the UTS of structural mild steel is not 260 N/mm2.
Option D is incorrect because the UTS of structural mild steel is not 520 N/mm2.
