Question Garage Shelving

I want to put up some heavy duty shelves in my garage for some easily accessible, yet very heavy equipment (units 2 - 10Lbs each, got about 30 or 40) My idea is to use lag screws to attach a bracket every stud, and on the other side of the bracket have a 2x4 attached horizontally, and attach like a (couple?) 2x6 or something across those. My concerns however are
A) what’s the largest lag screw I can safely use on a 2x4, repeatedly (maybe 4 of these shelves, maybe more) without jeopardizing the structural soundness of the wall, and
B) Is there a formula for determining how much weight I can have on a wall?

I wouldn't use too many lag screws, maybe one at the top of the bracket, and 1 1/2" screws at the bottom. Most of your weight at the bottom is vertical weight, while your rotation will be at the top. You can overkill fasteners, and deplete the holding power of the wood by adding too many. What type brackets do you plan on using? How wide (Deep) will your shelves be?
