counterweight calculation

[Donald Haxhiu Work]

Good morning. You would know how kindly I have to counterweight and what calculation you do to know. on this 2 meters wide hopper weighing 65kg. the counterweight I wanted to put it behind the fulcrum on both sides. but no I do not know what weight to put and at what distance from the fulcrum. (the hopper goes up with one hand on one side.) so counterweights have to do all the work practically. so as to ensure that with a human force I can lift the hopper (from one side). Could you please tell me what calculation you do to know how much weight I have to put behind to easily raise the hopper?

pull out the center of your hopper system where you apply the weight force (tramoggia+material), then apply two forces, one for counterweight and one for force in your arm (intensive as limb) you want to use to lift your system.

determined the center of the object and the center of rotation, as well as the distance from the wind to the handle will make the balance of moments around the center of rotation. therefore revenues the only unknown.

I think I didn't understand. You would make me gentimate the formula or the calculation and write it here, so I'll study it. Kindly. you should have all the data on the png. regarding the material is stainless steel

even if the forces applied are not all on the same level of the fulcrum, you must always consider them vertical, as you must horizontally consider the relative distances from the fulcrum.
identified the center of the overall durable weight, multiply the latter for its horizontal distance from the fulcrum and determines the resistant moment. that by balance must be equal to the moment generated by counterweights.

I thank you so much, now I understand
