$$ M_max = \fracwL^28 = \frac2 \times (20)^28 = 100 \text kip-ft $$ (Convert to kip-in: 100 * 12 = 1,200 kip-in)
Example:
A typical "simplified design" PDF will include these non-iterative formulas: simplified design of steel structures pdf
: Steel is an ideal candidate for simplified methods because it is a homogeneous, predictable material 2. Primary Methods of Analysis $$ M_max = \fracwL^28 = \frac2 \times (20)^28
