As per ASTM:C-42, the preferred length of the capped or ground specimen is between 1.9 and 2.1 times the diameter. If the ratio of the length to the diameter (L/D) of the core exceeds 2.1 reduce the length of the core so that the ratio of the capped or …
Briefly, the design procedure for Ductile Iron pipe includes: 1. Design for internal pressures (static pressure plus surge pressure allowance). 2. Design for bending stress due to external loads (earth load plus truck loads). 3. Select the larger resulting net wall thickness. 4. Add an 0.08-inch service allowance. 5. Check deflection. 6.

Note that this maximum bolt stress is NOT the same as the allowable stress in ASME design calculations, which is typically only 25 percent of yield. This stress limit is much higher because the ASME Code calculations are meant to force the design to have a significant safety factor, and the design stresses are therefore low.
Compared to mild steel, cast iron has (i) High compressive strength (ii) High tensile strength (iii) Low compressive strength (iv) Low tensile strength The correct answer is The compressive strength of perforated bricks should not be less than
It can be determined by following the steps given in any of the Standard Methods for Refractory Testing like - ASTM, Indian Standards (IS), Ghost, DIN etc. CCS of refractories is determined by placing a suitable Refractory Specimen on a flat surface followed by application of a uniform load to it through a bearing block in a standard mechanical or hydraulic compression …

The compressive strength of the stone depends upon-Quality and type of stone; Process and degree of weathering; Number of cracks and joints; Planarity and continuity of seams and foliations. The table given below shows the crushing strength of various stones.
a thick column subject to failure by crushing rather than by buckling. Failure occurs when the direct stress from an axial load exceeds the compressive strength of the material available in the cross section. An eccentric load, however, can produce bending and result in uneven stress distribution in the section
Cast iron is a ferrous metal, an alloy of iron with 2 to 4.5% carbon and 3.5% silicon. Compared to tensile strength cast iron is strong in compressive strength. This is because cast iron is having 2 to 4% carbon in it which makes it brittle in nature and all brittle materials are comparatively stronger in compression than in tension. Important ...
A laboratory study is carried out to characterize the effect of basicity (varying 1.5–3.5) on magnetite iron ore pellets containing TiO 2 (content 5%).
1. Introduction. Since the 13th century, people have been manufacturing concrete, that is still most popular building material all over the world (The Invention, 0000).In year 2020, it was estimated that almost 14 billion m 3 of concrete was produced and was further projected to grow about 68 % more by the end of year 2050 (Cement and concrete around, 0000).
The compressive strength of coal, and its variation within and between seams, was determined for four Pennsylvania coal seams (Pittsburgh, Sewickley, Upper Kittanning and Lower Kittanning). Large coal blocks were obtained from 12 coal mines (three mines per seam) and cut into 50-mm (2-in.) cubes using a low-speed saw. The cubes were tested for …
The crush strength seems to always be lower than the compressive strength. My understanding is that bare compressive strength is for a core specimen tested by itself and stabilized compressive strength is for a core specimen bonded to facesheets, so when analyzing sandwich panels the stabilized compressive strength values are appropriate. What ...
However, the impact of burning bottom ash on the strength and carbonation of concrete cannot be ignored. As a high-strength and high-toughness metal material, the …
Since brittle material is strong in compression but weak in tension whereas its shearing strength is in between its compressive strength and tensile strength. Ductile material is approximately equal to strong tension and compression but weak in shear. Case-1: Brittle material in torsion. Since brittle materials have minimum tensile strength.
Hi I'm a high school student and need help with the calculations for a bike design. I am required for the design to use 1.5" mild steel square tubing at 1/16" thick for it. I need to know what the strength of the tubing is before i can make or tweak the design. ... Crush Strength Of Donut Shaped 1.5 x 1.5 Square Tubing. Apr 17, 2023; Replies 4 ...
A crusher was used to crush a material with a compressive strength of 22.5 MN/m^{2}. The size of the feed was minus 50 mm, plus 40 mm and the power required was 13.0 kW/(kg/s).

We know that the torque transmitted by the shaft, key and muff, 2. Design for sleeve We know that outer diameter of the muff, D = 2d + 13 mm = 2 × 55 + 13 = 123 say 125 mm Ans.
parameters like cold crushing strength and shatter index of iron ore pellets are very critical for their handling and use. Cold crushing strength (CCS) of iron ore pellets varies widely from as low as 80 Kgf / pellets to as high as 350 Kgf /pellets depending upon the input material quality and the process variables. The most preferred range of ...
