Arunda Load Calculator

Determining the size of dovetail assemblies (joist to stringer type)

Calculus is a program that calculates the allowable load of your Arunda assemblies for common scenarios using a joist to stringer type of joint. Due to the many parameters involved in load calculations, other types of assemblies require different calculations specific to each.

Calculate load

Result

Vd1
Size determined by the tenon’s shearing force (tenon strength)
Vd2
Size determined by the support on the stringer (mortise strength)
Allowable value
The smaller of Vd1 or Vd2 is used as the allowable load for load calculations)

1 kN = 100 kg
