How many lbs Can an egg hold?
The strongest part of the eggshell lies at the top or bottom point of an egg. Therefore, an egg doesn’t break when you apply pressure at the peak points of both the ends. Also, the curved shape of an oval shaped egg is the strongest part since it participates in distributing weight and force evenly through the entire structure.
Eggs are easily cracked if they hit any hard surface because the shell of the eggs are fragile. But how the egg shells in this experiment managed to hold the heavy weight!! Because the dome shaped egg shells provides strength and support a great deal of weight.
The applied force and the amount of weight distributed by the egg shells decides the amount of force an eggshell can withstand. Actually, to break an egg, it requires a little more than 5 ½ pounds of force. What is the strongest part of an egg shell?
The average egg weighs approximately 57 grams or two ounces. Of this weight, the shell constitutes 11 percent, the albumen 58 percent, and the yolk 31 percent. Q: What is the weight of an eggshell?
Usually, it takes a little more than 5 ½ pounds of force to crack an eggshell — much less than the weight of a human being — but the precise amount of force needed depends on the direction in which that force is applied and how much the force is distributed (or not) over the surface of the shell.
The egg is strongest at the top and the bottom (or at the highest point of the arch), which is why it does not break when pressure is added to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point.
Chicken eggs were found to have a compressive strength of 100 lbs, whereas ostrich eggs gave values of more than 1000 lbs. Size and shell thickness were the most important factors in determining shell strength.
The diameter of a “large” chicken egg is about 1.75″ and the typical shell thickness seems to be around 0.023″. Thus, the cross-sectional area of the shell wall is approximately 1/8 sq in, or 8×10-5 m2 which, when combined with the ultimate strength, theoretically will support a 1.4×104 N load (3,000 lbs)!
Eggshell strength is generally measured using either direct tests, such as non-destructive deformation (Voisey and Hunt, 1974; Altuntas and Sekeroglu, 2008) or destructive fracture force (Voisey and Hunt, 1967a,b;Amer Essa, 1998) of an egg under quasi static compression between two parallel plates, or indirect tests.
Can eggs hold weight? The closer to normal, the more weight the egg should withstand. It is worth the extra Page 3 Egg Crusher spsnational.org/outreach 3 time to make sure it is standing up as straight as possible, a properly placed egg can withstand over 300 lbs.
The shell of a hen’s egg weighs only about one-fifth of an ounce, and it’s made from calcium carbonate that’s just over one-hundredth of an inch thick. In perfect conditions, that thin layer allows an egg standing on end to bear a 130 pound weight without breaking.
Testing by SPS found a wide range of maximum loads from ~100 lb to some as high as +300 lbs for standard, large eggs. Explain to the audience that the reason the egg can withstand such forces is because the foam decreases the pressure the egg experiences.
