I have seen the glass floor broken as a result of sag due to insufficient support. The sides are beams, but the glass floor sags and... -
Herman Trivilino replied to the thread Undergrad Compare Bending Resistance of Dimension Lumber used as Joist.Has anyone ever seen an aquarium stand sag? Don't the glass panels of the aquarium form beams? -
Herman Trivilino replied to the thread Undergrad Compare Bending Resistance of Dimension Lumber used as Joist.Yes. Each corner post does that. -
Herman Trivilino replied to the thread Undergrad Compare Bending Resistance of Dimension Lumber used as Joist.I thought that load was carried by the aquarium itself. -
Herman Trivilino replied to the thread Undergrad Compare Bending Resistance of Dimension Lumber used as Joist.It seems to me that the horizontal members are not load-bearing so the concern over their strength is unwarranted. Virtually all the... -
Herman Trivilino replied to the thread Undergrad Comparing the time of two moving clocks.E2 and E3 are different events. Of course the clock readings are different. Would you expect leaving for home and arriving at an event... -
