a truss is said to be rigid when there is no relative motion of any point on any member of the truss with respect to any other point on any other member of the truss. in other words, a truss is said to be rigid when the distances between any two points on the truss remain constant at all times.

A bucket crusher is a crusher inside a bucket that is attached to an excavator and so used.

What is the difference between ideal and actual cycle?

ASTM A105 and ASTM A105N are both specifications for carbon steel forgings used in piping applications, but there are some differences. Here's a quick overview:

1. **Chemical Composition:**

• **ASTM A105:** This specification covers flanges, fittings, valves, and similar parts for use in pressure Specifies standards for forged carbon steel piping parts, including: Ambient conditions and higher operating temperatures of the system.

• **ASTM A105N:** The suffix "N" indicates that these materials are normalized. Normalization is a heat treatment process that refines the grain size and improves the mechanical properties of the material.

2. **Heat Treatment:**

• **ASTM A105:** The standard A105 material is typically supplied in the as-forged condition, and it may or may not undergo additional heat treatment processes.

• **ASTM A105N:** The "N" designation indicates that the material is normalized, implying that it has undergone a heat treatment process to improve its mechanical properties.

3. **Mechanical Properties:**

• **ASTM A105:** The mechanical properties are specified without any mandatory heat treatment.

• **ASTM A105N:** The normalization process is intended to improve the mechanical properties of the material and provide better strength and impact resistance.

4. **Applications and Applications:**

• Both A105 and A105N materials are widely used in forged carbon steel piping components for a variety of applications, including: B. High temperature and pressure applications in the oil, gas and petrochemical industries.

It is important to note that specifications and requirements may vary depending on the specific version or revision of the ASTM standard. Always refer to the latest edition of the relevant ASTM standard for the most accurate and up-to-date information. If you are working on a specific project or application, we recommend referring to the project specifications or contacting a materials engineer to ensure that the correct material is selected for the intended use conditions. .

moments are defined as r x f. if you have member [x,y,z] and force [u,v,w] being applied to the end of it you take the cross product, [w*y-v*z,U*z-w*x,v*x-u*y]. if the member and force are perpendicular just multiply them and if it creates a clockwise rotation it is negative.

To ensure better temperature measurement on a stainless steel microtube, you can use a high-quality, accurate temperature sensor such as a thermocouple or resistance temperature detector (RTD). Properly calibrating the sensor at various temperature points and ensuring its secure attachment to the microtube will improve measurement accuracy. Additionally, minimizing any external factors that may affect the temperature reading, such as ambient temperature fluctuations or heat radiation, will further enhance measurement precision.

A closed system is termed as a control mass because it does not exchange mass with its surroundings. This means that no mass enters or leaves the system, and therefore the total mass within the system remains constant. This allows for the analysis of the system's energy changes and thermodynamic processes in isolation, making it a control mass for studying energy transfers and conservation.

Yes, the bulk modulus of elasticity increases with pressure. The bulk modulus measures the resistance of a material to changes in volume under applied pressure. As pressure increases, the material becomes less compressible and therefore the bulk modulus increases.

The greatest stress that a material can resist before breaking is called the ultimate tensile strength. It is the maximum amount of stress a material can withstand without breaking under tension. Different materials have different ultimate tensile strengths, and it is an important property to consider for designing and engineering structures.

not only mechanical but every enginner earn upon their experience and the capability of their knowlwdge.. one can assume the starting package of maximum engineers for reputed companies varies from 2.5lac-4.5lac. and as the engineer gains experience his salary also goes on increasing.

A ball valve is a contrivance by which a ball, placed in a circular cup with a hole in a bottom, operates as a valve.

Thats all i can think of right now

yes it can happen. my baby rabbit had a stroke too.

Yes, it can happen. If your rabbit is still alive, you should take it to the vet immediately so you can be sure and either save its life or let it die peacefully.

Basically sawdust and resin compressed under very high pressure. It's typically used for counter tops, furniture, speaker boxes and many other indoor applications.

Yse, basically you are right.

Medium Density Fibreboard (MDF) is a reconstituted wood panel product. It is a dry-processed fibreboard manufactured from wood fibres, as opposed to veneers or particles, and is denser than plywood and particleboard. MDF has an even density throughout and is smooth on both sides.

MDF is reconstituted into wood sheets in a variety of widths and lengths. Bonding is achieved by the addition of synthetic resin adhesives, which are cured under heat and pressure. Paraffin wax is added to assist with water repellency, while other chemicals can be added during manufacturing for more specific protection.

MDF is primarily used for internal use applications, in part due to its poor moisture resistance. It is available in raw form with a fine sanded surface or with decorative overlay such as wood veneer, melamine paper or vinyl.

*Base-

is a foot or base of the drill tool, which is usually made of cast iron, which functions to provide stability and to support the upright column.

* Table

is a work table to put things on to be drilled. Surface of the table can be 90o angle formed with the column, and can be moved up, down, angled and rotated on the column . The form of a table can be round or square.

* Drilling head (head gear)

is the head gear that is attached at the top end of the column. This section consists of components that raise or lower the spindle. Spindle axis is not rotating, but will only move up and down inside the head

At the lower end of the spindle is the chuck, which serves to hold the drill bit.

* Power transmission

is the part that transmits power which comes from the electric motor. This is transmitted by using a pair of opposing pulley stacks and a V-belt. With a combination of comparative size pulleys the speed of the spindle can be adjusted.

* Hand-feed lever

is a tool that is used to control the up/down movement of the drill spindle.

* Depth stop

regulates the depth of spindle movement.

it depends on the mix and application. It varies between 9 and 12GPa (1300 and 1700 ksi)

The average annual salary for an engineer in the United States is $70,000. Salaries can vary based on location and experience. The low end of the scale is $47,700 and the high end of the scale is $90,340.

After diploma there is a good salary scale companies provide very good packages for diploma holders on an average a diploma holder receives salary in between 3lpa- 4 lpa which is a very good package for a fresh candidate...

Reliability is not measured. Reliability is an estimation, typically probablistic.
