Hi, i'm having trouble with loads in solidowrks simulation.

I am trying to apply remote mass do beam elements ( i have created pivot with 3 nodes) i wanted to connect my mass to the center node but it's inacvite, how can work around it ?

My next idea was to make frame from trusses that connect all nodes, with one that should distribute mass to the pivots, but how to apply mass to the node i don't have this option.

I can't apply forces because i want to "make" them from acceleraction

Any ideas ?
