For small equipment mounting, let me introduce two simple methods: 1) Rigid Rotation Method (Classic) 2) Cantilever Method (Conservative approximation) Assume cantilever action, for which the applied load rotates about the point "A", and the rotation is restricted by the two bolts farthest from the point "A". Conclusion: I recommend ...

As mentioned in kamran's answer its very important that the bar is rigid. Otherwise the following analysis is not relevant. Although you don't seem to consider it this way, -if the beam is rigid enough-, then the fulcrum at the far left edge of the beam (not on B1, so the force there is not zero). The equation I derived is based on that assumption, which is ...

Assuming the lever is rigid enough not to bend to simlify our estimate: The lever will rotate about B1 bolt because it can not penetrate the concrete block. So B2 to and B3 will share the 288N proprtionaly to their distance from B1. Lets call their reactio RB2 and RB3 respectively. $$R_{B3} =(1250-742=508)/(1250-912=338)*R_{B2}= 1.5 R_{B2}$$ By substituting ...
