as title says, can any one help me with this?
for example if i want to build a long shelf to hold upto 50kg of material or anything for that matter how would you know what material sizes, thicknesses to use so it wont sag in the middle and will take the weight?
i realise that you could just add loads of supports and use really thick materials, but i dont want to be using 5mm material when 1.5mm will do if you get what i mean?
thanks in advance for your answers
