The strength of quartz depends on the flaw size. Typically the strength of quartz is about 8000 psi (55MPa) in tension. If severely flawed it could be as slow as half that value, and if it is stressed in water it could be even lower. If perfect without flaws it will exceed 40,000 psi (275 MPa). I would use about 6000 psi in general and use a large safety factor. Most codes use a safety factor of 5 for glass to be certain in case there are hidden flaws.

In shear I would use the tension value

A fillet weld in any single continuous weld
may underrun the nominal fillet weld size specified by
2 mm [1/16 in] without correction, provided that the
undersize portion of the weld does not exceed 10% of the
length of the weld. On the web-to-flange welds on girders,
underrun shall be prohibited at the ends for a length
equal to twice the width of the flange.

Ten meter water column is expressed as a column of water of 1,000 cm high with a section of 1 x 1 cm. This equals 1 dm3 of water which has a mass of 1 kg.

As such 10 meter water column exerts a pressure of 1 kg/cm2.

1 kg/cm2 = 0.980665 bar

Therefore:

1 m WC = 0.1 kg/cm2 = 0.0980665 bar

0.980665 bar = 1 kg/cm2 = 10 m WC

1 bar = 1.0197162 kg/cm2 = 10.197162 m WC

The six point technique of fault finding used in mechanical maintenance is called the hexagonal method. It also sometimes called the six sigma and is a process of quality control.

Integral stsrters are embedded with motorised valves. By using integral starter, one can control motorised valves by remotely and locally. Even it can indicate the motorised valves direction of rotation & its final position, Power failure detection , indicate motor winding temperature, auto phase correction and emergency shut down of valve.

my question is can you show me the animation of working crank and slotted lever type quike return motion mechanisum

It depends on the loading conditions of the beam, it will generally occur close to the middle of the span.

Stress occur everywhere in the beam.

Maximum occur at mid span and at support of simply supported beams and cantilever beams respectively - M. Velsamy, Mobile 9884585625

there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on

Peaking is deviations at vertical weld joints, while banding is deviations at horizontal welds of tank shell , regards engr waqas akram, any engg related questions can be asked at waqas429@hotmail.com

main two type of bearing used in steam turbine:(1)thrust bearing (2)general bearing

it's steel pipe without any processing and packing.

it will depend upon the load and moment applied on the beam.

Stress is the tension/compression force per unit area.
Strain is the ratio of change of length to the original length, due to applied force.
Tension is the applied force which tends to elongate the body.

Compressor Inlet Temperature sensorfor a Gas turbine engine.

Recrystallization temperature in metal working can be defined as the temperature at which the plastic deformation takes place perfectly. The stresses induced during the process is are grater than the yield strength and less than the fracture strength.

Proof machining means>> If part have too much dispensable material to remove through out machining than machining is done on the same to remove all material till it will have only 2~3 mm to achieve its final dimensions , this process is called proof machining or if part have 1~2 mm material to remove for coming it final dimensions then Cutting tool path proving done & is called proof machining.

GM500M: Mechanical and Material Requirements for Metric Externally Threaded Fasteners.

This standard covers the mechanical and material requirements for six property classes of carbon and alloy steel externally threaded metric fasteners in nominal thread diameters M1.6 to M36, inclusive, suitable for use in general engineering applications. Products included are bolts, screws, studs, U-bolts and sems and hardness of HRC39 max. Tapping screws, thread rolling screws, self drilling tapping screws and set-screws are NOT included.

The term "stud" as referred to herein applies to a cylindrical rod of moderate length, threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared or similar products which are more closely characterized by requirements shown herein for bolts.

For specification purposes, this standard treats U-bolts as studs. Thus, wherever, the word "studs" appears, "U-bolts" is also implied. U-bolts covered by this standard are those used primarily in the suspension and related areas of vehicles. (Designers should recognize that the "U" configuration may not sustain a load equivalent to two bolts or studs of the same size and grade; thus actual load carrying capacity of U-bolts should be determined by saddle load tests.)

Requirements for the 6 property classes, 4.6, 4.8, 5.8, 9.8, and 10.9 are essentially identical with requirements given for these classes in ISO 898/1 and ASTM F568.
