How do you download the solution manual of engineering mechanics of solids by Egor P Popov for free?
You can go to the publishers website, and if you can be identified as an instructor and such a book is available, you can often get it for free.
If you are a student, you're better off if you dig through the book and other materials to find the solutions. You will remember it better and that will help you in the courses that follow and in the real world.
How many delayed cokers are there in the world?
Please refer to the link which indicates about 218 Delayed Cokers licensed around the world as of early 2010.
What are static and dynamic lines?
. The guy above said it correctly static no give really dynamic changing or give essentially it strecthes. These two types are usually referred to when climbing lines are involved some ropes you want to give in case of fall the 10-20 ft from your last point in which you set the line. You want static when you rappel down a rock face because you do not want it to give but consistently bear your weight as you descend.
What is arcing length in steel melting?
Please rephrase the question. Are you describing an electrical furnace or the welding process?
Why do engineers do not design bridges of rubber?
Engineers do not design bridges from rubber primarily due to its poor structural properties, such as low tensile strength and limited load-bearing capacity. Rubber is also susceptible to degradation from environmental factors like UV exposure and temperature fluctuations, which can compromise durability and safety. Instead, materials like steel and concrete are preferred for their strength, longevity, and ability to withstand heavy loads and various environmental conditions.
When is an auxiliary view needed?
An auxiliary view is needed when an object has features that are not parallel or perpendicular to the primary views, making them difficult to accurately represent. This occurs often with inclined or oblique surfaces that cannot be fully depicted in standard front, top, or side views. By creating an auxiliary view, these features can be shown in true shape and size, facilitating better understanding and communication of the object's geometry.
Is it uncommon for engineers to have difficulty writing papers?
It is not uncommon for members of any technical profession to have trouble writing papers. Those who can write reasonably well are more valuable and more likely to advance.
Anyone who has difficulty writing understandably can find courses that are designed to help learn how to do that better.
What is standard cell characterization?
Standard cell characterization is determining electrical properties of a circuit (timing, power, noise, capacitance etc) using simulation.
See www.paripath.com, a provider of Standard cell characterization software, for more information.
Why should expansion loops be incorporated into a system?
In a pipeline system, expansion loops, which may actually be ahorseshoe or w-shape besides a loop, provide a tolerance for the pipe when it experiences a thermal expansion or contraction.
What are the different types of MIDI messages?
Hi there, assuming you're asking about Musical Instrument Digital Interface ..
The most common messages you'll encounter, without any overwhelming technical explanation:
Note on/off messages - Sends the note pitch to be triggered (such as C3) as well as as a velocity (0 -127).
Pitch Bend Messages - most commonly used by pitch bend wheels on synthesizers to "slide" notes up and down.
Continuous Controller Messages - assignable numbers mostly with a 0 - 127 range that can control filters, LFO's, effect parameters. Most commonly used on synthesizers for pitch modulation (such as a sax playing vibrato)
Program Change messages - tells the receiving MIDI device to change to a corresponding patch or program location etc. (changing sounds)
Aftertouch (Channel and Poly) - channel aftertouch sense the *pressure* applied to a held key and whatever aftertouch is assigned to trigger .. will affect all the notes on that MIDI channel. This is the most common type of aftertouch on synths. Poly Aftertouch is channel specific, as well as each individual note it tracks. This is rare on most modern synths because it's expesive to build.
PCB stands for "Polychlorinated biphenyl" in chemistry and environmental protection. PCB stands for "printed circuit board" in electrical engineering.
How do you calculate shaft power?
Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft)/ 60
Torque of a solid shaft is given by (pi/16)* (Shear stress of material of shaft) * (Dia of shâft3).
Who invented of first esteem engine?
I don't know about the 'first esteem engine' but grammar has definitely been invented before. Take an English lesson, perhaps?
Is Stephenson's rocket still in existence?
Yes, it is to be found in the Science Museum in London.

A torch works using the concept of combustion. There are two main parts of a torch: the top, where the fuel is, and the bottom, the part that is held in the hand or inserted into an artificial torch bearer. When the fuel reaches a high enough temperature, combustion begins. This is when oxygen from the surrounding air starts to combine with the fuel on the torch, releasing energy in the form of light and heat. Many modern torches use a hydrocarbon as fuel, such as lighter fluid, while older, more primitive torches simply use natural sources of carbon, such as wood. Torches also have symbolic meanings, such as hope and enlightenment, but torches also symbolize death if shown pointing downward.
