I am looking for the formula to figure strength to weight ratio for a dome that I built for a project

It depends on how thick of steel you're aiming to cut. But most job shops process steel with either laser cutting (for thin steel) or waterjet cutting (for up to 12" thick)... or machining.

The general rule that is mostly true a lot of the time is that "caliber" is the diameter of the bore (the hole inside the barrel through which the bullet passes) as expressed in decimals, using inch units of measure. So a "thirty caliber" rifle would have a bore of .30 inch or 30/100 inch. A "twenty two caliber" gun fires a .22" diameter bullet.

But "caliber" also means a particular name of a specific cartridge of a certain height, weight, width, angle, and gunpowder charge. For example, a .22 "long rifle" bullet weighs 40 grains and moves at an initial velocity of 1000 feet per second. But a .220 Swift rifle cartridge fires a bullet of the same diameter, but longer and heavier, and at over 3,000 feet per second. Two different caliber cartridges, but in each case the hole in the rifle's barrel is about 22/100 inch.

I was not the question.

Fy = 235Mpa

Fu = 400Mpa

Discontinuous chips are formed during machining processes where the material is removed in an irregular, non-uniform manner, often resulting in smaller, fragmented pieces. In contrast, segmented chips are produced when the chip forms in distinct, separate segments or layers, usually due to a combination of cutting conditions and the material properties. Segmented chips can indicate a more efficient cutting process, while discontinuous chips may suggest issues such as tool wear or poor cutting parameters. Overall, the chip formation type can provide insights into the machining conditions and material behavior.

DTS-I means "Digital Twin Spark ignition".....

The modulus of elasticity, or Young modulus, has dimensions of force per area

In English system that is pounds per square inch; in metric system that is newtons per per square meter, or Pascals

4-12

z.p school manegment

It is thicker than 1/8th inch thick steel.

Yes

workshops,computers

According to ISO R286

The tolerance for a 16mm H9 hole is:

16mm +0.000mm

16mm +0.043mm

Shear stress in fluids is influenced by their viscosity, which is a measure of a fluid's resistance to deformation. Water has a lower viscosity compared to mercury, meaning it flows more easily and can develop shear stress more readily under applied forces. However, due to the cohesive forces in mercury, it exhibits higher surface tension, which can affect how shear stress manifests in different contexts. In general, while water can develop shear stress quickly due to its low viscosity, mercury's unique properties result in different behaviors under shear.

duhhhh

Not even in top 150 in present scenario.Don't go for ranking of UPTU colleges all are same category all are waste except all government colleges.UPTU gives u just the eligibility to do something better in future

Because the more the load the more the temperature.

Materials which have a low to zero moisture content, where the individual particles do not bond and material will flow at a relatively low angle due to the low particle friction.

Answer

They are different measurements of a material under a load.

Stress is the amount of Force per area. If you pull on a bar that has an area of 1/2 square inches with a 5000 pound force then the Stress would be the Force divided by the Area or

Stress = 5000 LB /divided by/ 1/2 In2 = 10,000 Pounds per Sq Inch (psi)

Strain is the measurement of the deflection of a material under a load. This measurement is very small and it is described in terms of Inches of deflection per the original length in Inches of the part.

Strain is measured as In/In.

Under a given load, the stress will be present and the part will deflect. The chair you are sitting in has deflected ever so slightly while carrying your weight.
