In general, load calculations are typically based on beam's both ends supported for structural safety. Selection Example Step (1) Find a point on the Y (Load) axis for the applied load P (Unit: N)*1. (2) Find a point ( ) on the X (Length) axis for the extrusion length. (3) Draw a horizontal line from and a vertical line from , and name the intersection of the two as . (4) Find a point on the right hand Y axis for the Cross Sectional Moment of Inertia of the extrusion used. (5) Draw a horizontal line from , and draw a parallel line to the graph's diagonal lines from . (6) Name the intersection of the lines from (5) as . (7) Draw a line UP from and locate an intersection corresponding to the extrusion support method used. Result: According to the example values used and the calculation based on the values, the deflection amount would be 0.3mm when the extrusion is supported at both ends. *1. Conversion: 1kgf=9.80665N (Ex.) 81.6kgf=800N t MISUMI defines the Load Capacity (Max Allowable Load) to be a deflection 1/1000 of the extrusion length.
