How thick does a 2X2 foot piece of glass need to be to hold 50 lbs supported only at the corners?

If the load is uniformly distributed over the area it needs to be 0.21 inch thick using a safety factor of 5 on the glass strength to account for flaws. The support at the corners must not be a point load but rather distributed by a soft or plastic pad

What is tempered glass glass?
thick commercial glass panels formed under pressure. when cooled the temsion of the pressure is locked into the crystal structure making them very resistant to damage from a blow to their faces (but not to their edges and edge corners)

How fast does a tennis ball have to go to break tempered glass?
You need to know the area of the glass, its span, how it is supported, and how thick it is; also you need to know the stiffness of the tennis ball; so this is a complex problem.
What is concave lenss?
concave lense is a piece of smooth glass that is thick from the edges and thin from centre and is used to diverge light rays.
How thick is 10 mm glass?
It is 10 mm thick.
How much force can ordinary glass withstand?
The amount of force an ordinary glass can withstand depends on it's thickness. A 1/4-inch thick piece can withstand approximately 292 lb per square foot.
How thick is the glass in SeaWorld?
It varies from 2-75 inches thick.
If a hot piece of thick glass is clipped in cold waterit breaks.Give reason?
The edges of the thick glass will cool faster than the center portion since the glass has low thermal conductivity. This produces a thermal gradient in the glass putting the outside edges in a state of tension stress. Glass fails in tension at a low value if any flaw exists on the edge surface.
What was needed to make bulletproof glass?
Alternating layers of glass and plastic resin. Truly bulletproof glass must be at least 4 to 6 inches thick! I've seen samples of such glass from WW2 bombers in museums. Modern bulletproof "glass" probably uses plexiglass plastic instead of real glass though. Note: a thick enough piece of ordinary glass is bulletproof by itself. Telescope mirrors (several feet thick) have been shot and although damaged the bullet did not pass through and after removing the bullet, drilling out the hole, and painting the inside of the hole black the telescope was returned to operation with no detectable loss of function.
Is a glass a structure?
