Answer:
c < a = b
Explanation:
The tensile stress = Force applied/(Cross sectional area)
(a) The applied force = 200 N
The cross sectional area = 1.00 mm² = 1 × 10⁻⁶ m²
The tensile stress = 200 N/(1 × 10⁻⁶ m²) = 200,000,000 Pa = 200 MPa
(b) The applied force = 200 N
The cross sectional area = 1.00 mm² = 1 × 10⁻⁶ m²
The tensile stress = 200 N/(1 × 10⁻⁶ m²) = 200,000,000 Pa = 200 MPa
(c) The applied force = 100 N
The cross sectional area = 2.00 mm² = 2 × 10⁻⁶ m²
The tensile stress = 100 N/(2 × 10⁻⁶ m²) = 50,000,000 Pa = 50 MPa
Therefore, the tensile stress from smallest to largest are;
(a) 50 MPa, < (b) 200 MPa = (a) 200 MPa
Therefore, we have;
c < a = b.
