Hi!<\/p>\n

I have a crane structure in AIM 2020 R1. The structure itself weights cca 650kg and other suppressed parts added as Point Mass cca 1200 kg, so the sum mass of the model is cca 1800-1900kg. Amplified Earth Gravity (Inertial Load) is 15.2 m\/s2 so the full downward acting force in the system equals 15.2*1900kg = 29 kN. Nonetheless, the Reaction Force is only 8kN as you can see on the attached picture.<\/p>\n

Can you explain this difference please? WBPZ file attached.<\/p>\n
