1. Solid Steel Shaft Analysis
Mechanical EngineerBackground
An engineer is designing a solid steel drive shaft and needs to verify its bending resistance.
Problem
Calculate the second moment of area and section modulus for a solid circular shaft with a diameter of 100 mm.
How to use
Select 'Solid Circle' as the shape, enter 100 for Diameter D, set decimal places to 4, and run the calculation.
{
"shape": "circle",
"D": 100,
"decimalPlaces": 4
}Outcome
The calculator outputs a second moment of area (I) of 4,908,738.5197 mm⁴ (490.8739 cm⁴) and a section modulus (Z) of 98,174.7704 mm³.
