Unit Weight of Metals

Dear Readers,
Now you may well aware about to calculate the weights of steel structures. During construction activities you want to calculate the weights of steel members you will do it absolutely. However if the material is other than steel?It is very simple, formula is same but the specific weight (kg/Cum) is varies.
Example below illustrate to calculate  plate size is 1500 X 1500 X 6 with different material (Iron & Copper)
For Steel ( 7850kg/Cum or 7.85kg/sqm)
                = (1.5 X 1.5 X 6 X 7.85)
                = 105.975 kg
For Copper Plate same size (8930kg/Cum or 8.93Kg/sqm)
                = (1.5 X 1.5 X 6 X 8.93)
                = 120.555 kg
For Unit Weight of more metals listed below table
Hope above table would be more useful for Construction Engineers. If any queries please send your queries through contact form or send a mail to engineerdiary@gmail.com

Dear Readers,
This is continuation with my earlier post unit weight of ISJB, self would like to post the sectional properties of ISJB. I am sure this post would be very helpful to all engineers.
Properties of beams are having two parts. One part is Physical dimensions and another part is sectional properties of Beam. Basically dimensional part contains depth and width of section, Thickness of Web and Flange and Root Radius. Where as sectional properties contains Moment of Inertia, Radius of Gyration and Section Modulus. These are useful for design engineers. Click on picture to enlarge.

Bearing Designations

Dear Readers,

As you well aware that bearing is a device that supports, guides, and reduces the friction of motion between fixed and moving machine parts. All standard bearings have a characteristic basic designation it consist of basic numbers and supplementary symbols (Prefix and Suffix). If you know the observation of bearing number you may proceed further without any delay of your activity / job. You know prefix and suffix details then it is an excellent.  
The first digit (or letter) designates the bearing type, the second and third digits indicate the dimension series to which the bearing belongs. The second digit represents the width (or height) series and the third digit the diameter series. The three first digits together designate the bearing series.
The two last digits indicate the bore diameter. For bearing with bore diameter between 20 and 490 mm is obtained by multiplying the two last digits by five. For bearing with bore diameter greater than 490mm the bore diameter is directly indicated after an oblique (Ex.511 / 500). Special coding applies for bearings with bore diameter less than 20mm.
Types of bearing, prefix and suffix details will follow my next post

Dear Readers,

Wish you a Happy Engineer Day-2013

Engineer dairy is very much proud to publish this article during the Engineer Day. Bearing is one of the wonderful engineering innovation in this world and it is biggest mile stone of engineering industry. Any rotation parts with out bearing is un-imaginable. From children's toys, household utilities to aeroplane and space equipment everywhere bearings are involved.
Bearing is a device that supports, guides, and reduces the friction of motion between fixed and moving machine parts. Bearing is primarily used in between rotation parts. The main function of rotation part is transmit power from one end to another end. For transmitting power, it needs a good support to ensure stability and frictionless rotation. The support is known as “bearing”.
The bearings are classified in to two main category. One is plain or Slider bearing, another one is Rolling or Anti friction bearing. Under this main category there are numerous different kind of bearings that are designed to handle radial load, thrust load or combination of the two loads.
Sliding Bearing. It is a simple plain bearing, it is classified in to Journal bearing, Footstep bearing and collar thrust bearing.
Ball and Roller Bearing. These are known as anti-friction bearings, widely used in industries. It is further classified as follows
Ball bearings (Self-aligning ball bearings, Double row angular contact ball bearings, Double row deep groove ball bearings, Single row deep groove ball bearings, Single row angular contact ball bearings & Four-point contact ball bearings)

Roller bearing (Spherical roller bearings, Tapered roller bearings, Cylindrical roller bearings, Needle roller bearings)
Thrust Bearing (Cylindrical roller thrust bearings, spherical roller thrust bearings, Thrust ball bearings)

American Wire Gauge (AWG)

Dear Readers,

This is in continuation with my earlier article of Gauge system and SWG.Hope you may familiar with the gauge system. Let us discuss this article about AWG.

American wire gauge (AWG), also known as the Brown & Sharpe wire gauge. Non-ferrous metals like copper, aluminium and other wire materials (meaning those that do not contain iron) are using the American Wire Gauge (AWG), but is most frequently applied to copper household electrical wiring and telephone wiring. Typical household wiring is AWG number 12 or 14. Telephone wire is usually 22, 24 or 26. The higher the gauge number, the smaller the diameter and the thinner wire. 
The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb - for every 6 gauge decrease, the wire diameter doubles. Dimensions of American Wire Gauge is below.

One Million Page View

Dear Readers, 

I'm proud to announce that Engineer Diary blog has just crossed the One Million Page Views (1,000,000) threshold since start of the blog and of course it is a milestone for engineer Diary blog. I so excited to write this!. This Milestone brings me to encourage myself to keep at this hobby, to minimize slacking, get better at doing things and more exciting blogging journey. I would like to thank you readers, because you peoples helped make this possible.

I have been watching the page view counter closely the last few days, and knew that it is only a matter of time before we had cross the seven figure boundary. When i started the blog just over three years ago, reaching such number was not even a goal. Now that I have reached it and it does feel like a goal. The Internet is an awfully big place, and in Internet terms one million is a tiny number. Whatever it is worth, a million page views indicates something related to a wide readership.

Standard Wire Gauge (SWG)

Dear Readers,
Wish You a Happy May Day-2013
This article let us discuss about Gauge systems. This systems are used to represent the thickness of the wire or diameter of the wire. In Great Britain wire gage has been legalized. This is called the Standard Wire Gage (S.W.G.), formerly called Imperial Wire Gage.
 Other main systems for measuring gauge are American Wire Gauge (AWG), Standard Wire Gauge (SWG) and Birmingham Wire Gauge (BWG). However AWG and SWG are widely used throughout the world. In general ferrous metals are using Standard Wire Gauge (SWG) and Non-ferrous metals (meaning those that do not contain iron) are using the American Wire Gauge (AWG).
Wire diameter is a premier factor in determining the wire. Different numbering systems are used, depending on the type of metal. Inch and millimetre dimensions are used for Standard Wire Gauge (SWG). No. 7/0 is the largest size (0.50 inch or 12.7 mm) in diameter, and No. 50 is the smallest( 0.001 inch or about 25 µm) in diameter. Overall as the gauge number decreases, the thickness of the wire increases. Wire gauge can refer to both electrical and mechanical.
