Remember:	1m = 1000mm ; 1N/mm = 1000N/m ; 1Nm = 1000Nmm
	1ft = 12in ; 1lbf.ft = 12lbf.in ; 12lbf/ft = 1lbf/in

The above beam deflection and resultant force calculator is based on the provided equations and does not account for all mathematical and beam theory limitations. The calculator has been provided with educational purposes in mind and should be used accordingly. Unit conversion

Notation and Units

Metric and Imperial Units

The above beam design and deflection equations may be used with both imperial and metric units. As with all calculations/formulas care must be taken to keep consistent units throughout with examples of units which should be adopted listed below:

Notation

FBD = free body diagram
SFD = shear force diagram
BMD = bending moment diagram

a & b = span length under consideration, in or m
M = maximum bending moment, lbf.in or kNm
P = total concentrated load, lbf or kN
R = reaction load at bearing point, lbf or kN
V = maximum shear force, lbf or kN
