load test of steel frame for a 3D CNC mill
http://jwstolk.xs4all.nl/mill.htm

frame length        : 2.21 m
frame material      : 50x50x50x4mm steel U-beams
test load           : 4x25 Kg
resulting frame flex: 0.05 mm
software            : MegaPov 1.2.1
mechsim settings:
#declare E_steel        = 200*1e9;                // N/m^2 or pa

#declare A_U50x50x4     = ((50*50)-(42*46))*1e-6; // m^2

// choose a material and beam type:

#declare E_beam         = E_steel;                // N/m^2 or pa

#declare A_beam         = A_U50x50x4;             // m^2

// calculate stiffnes from elasticity and area:

#declare stiffness_beam = E_beam*A_beam;          // N/m


time_step 1/50000000
