Critical Stress for Cast Iron by NYC code Solution

STEP 0: Pre-Calculation Summary

Formula Used

Critical Stress = 9000-40*(Effective Length of Column/Radius of Gyration of Column)
S_w = 9000-40*(L/r_gyration)
This formula uses 3 Variables

Variables Used

Critical Stress - (Measured in Pascal) - Critical stress is required for crack propagation in a brittle material.
Effective Length of Column - (Measured in Meter) - The Effective Length of Column can be defined as the length of an equivalent pin-ended column having the same load-carrying capacity as the member under consideration.
Radius of Gyration of Column - (Measured in Meter) - The Radius of Gyration of Column about the axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass.

STEP 1: Convert Input(s) to Base Unit

Effective Length of Column: 3000 Millimeter --> 3 Meter (Check conversion here)
Radius of Gyration of Column: 26 Millimeter --> 0.026 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_w = 9000-40*(L/r_gyration) --> 9000-40*(3/0.026)

Evaluating ... ...

S_w = 4384.61538461538

STEP 3: Convert Result to Output's Unit

4384.61538461538 Pascal --> No Conversion Required

FINAL ANSWER

4384.61538461538 ≈ 4384.615 Pascal <-- Critical Stress

Cast Iron explanation

Cast iron is a class of iron–carbon alloys with a carbon content of more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured;
white cast iron has carbide impurities which allow cracks to pass straight through,
grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and
ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing.
