Question

A load 6 kN is to be raised with the help of steel wire find the minimum diameter of steel wire if dress is not exceed 110 N/mm

Answer 1

Answer:

D = 34.74  × 10⁻³ m

Explanation:

Given,

• Load = 6 KN = 6000 N

• Stress = 110 N/mm = 110 × 10⁶ Pa

THE FORMULA TO CALCULATE THE FORCE,

Force = Stress × Area

Area = Force/Pressure

→ πr² = 6000/110 × 10⁶

→ 3.14 × r² = 54.545 × 10⁻⁶

→ r = (54.545 × 10⁻⁶)/3.14

→ r = 17.371 × 10⁻³ m

∴ D = 2r = 2(17.371 × 10⁻³)

⇒ D = 34.74  × 10⁻³ m
