The maximum tensile force a rectangular steel bar of cross-section 20 mm % 10 mm can withstand, if it has a tensile strength of 800 MPa, is:
A) 16 kN
B) 25 kN
C) 160 kN
D) 2500 GN

Question

Quizplus · Accepted Answer

The maximum tensile force that a bar can withstand can be calculated using the formula:
Maximum Tensile Force = Tensile Strength x Cross-sectional Area
Cross-sectional Area = 20 mm x 10 mm = 200 mm² = 0.0002 m²
Tensile Strength = 800 MPa = 800 N/mm² = 800,000,000 N/m²
Maximum Tensile Force = 800,000,000 x 0.0002 = 160,000 N = 160 kN
Therefore, the correct choice is C.
