What is the minimum diameter of a steel wire if it is to support a mass of 80 kg.The elastic limit of steel is 5.0 × 10⁸ Pa. A)1.4 mm B)2.0 mm. C)1.0 mm D)2.0 mm

Question

Quizplus · Accepted Answer

The minimum diameter can be calculated using the formula for stress: Stress = Force/Area. The force is the weight of the mass (80 kg * 9.8 m/s²), and the area is π(d/2)². Solving for d using the elastic limit as the maximum stress gives approximately 1.4 mm.
