WebSciencePhysicsTwo wires - A and B - with circular cross-sections have identical lengths and are made of the same material. Yet, wire A has four times the resistance of wire B. How many times greater is the diameter of wire B than wire A? Two wires - A and B - with circular cross-sections have identical lengths and are made of the same material. WebHollow Cylindrical Cross Section The Area Moment of Inertia for a hollow cylindrical section can be calculated as Ix = π (do4 - di4) / 64 (5) where do = cylinder outside diameter di = cylinder inside diameter Iy = π (do4 - di4) / 64 (5b) Square Section - Diagonal Moments The diagonal Area Moments of Inertia for a square section can be calculated as
