The theory regarding How a Car experiences a bump does not appeal to me much.
The statement that
does not convince me much.
Anyway, my question is regarding the transmission of force through the spring and reducing the shock/jerk experienced by the passengers (just check if my...
When thre is a spring attatched to a certain body (like take the example of the suspensions/shock absorbers of an automobile) and a force is applied through that spring.
The automobile suspensions can be the best eamle for this discussion. We say that the force generated (which we experience...
Studiot,
Do excuse me if I've mistaken and misunderstood your intent behind the statement regarding ME previously. I regret my reaction sincerely.
Regarding the reinforced structure
Yes I can understand that the concrete and steel would not react chemically, but ultimately...
I am a qualified Mechanical Engineer so it is not some sort of Mechanial Engineer, though I may be lacking in experience.
Dear studiot :
My knowledge of elementary stress analysis and distribution (of UG level ) is sound enough and its certainly beyond the need of your scrutiny, and your...
It is evident from the condition of the reinforced section in practicality that the concrete and steel both undergo an extension or compression by the same amount, and that there is no slip between them.
So quite visually we infer that the Strain is same in both, and hence apply the same...
Didnt quite get it, can you please explain it - specially how exactly is force transferred through bonds that too frictional force ( nearly cohesion)
And also the forces in steel are either tensile or compressive ( depends on the type of loading it supports) and not shear , so can you alrify...
When we calculate the stresses in the section of a Reinforced Concrete column reinfored with Steel Rods, it is seen that the percentage Load carried by the Steel is much greater than the percentage area it contributes in the cross sectional area of the reinforced concrete section.
The load...
Thanks Mapes and Studiot for your replies.
I want to clarify on a few things. In the first place Studiot you have mentioned molecules for the example purpose, whereas I had a pure solid metal in mind so that the complication of having two different types of atoms bonding together to form a...
This is a question put to me by a colleague of mine which I don't quite know how to answer and has lead to a confusion ( or may be a misconception of physics)
The question is as follows:
When a solid rod is heated it undergoes a Free Thermal Expansion > means that the energy of the atoms...
and
WHy are you guys divertung the topic? And from where did the chain come in picture? I've not spoken about chains at all.
I am clearly mentioning about a simple mass ( say a block) kept on the ground ( so friction included) is said to be easily pushed than Pulled to move it forward...
Yep, Mike , that's what I've read ( rather explained by a person on a platform for engineering disussions) in one place.
And I'm in a dilemma about the correctness of the statement. ( I personally don't see any difference between the two, but this is just to confirm it and see if it actually...
1. I have heard the argument that "the Effort ( Force ) required to move a certain mass by Pulling is greater than the Effort required to move the same mass by Pushing it".
What is the truth regarding this statement and what causes the difference in the applied force to move the same...
@ gmax and @ Fox Commander: Both of you, Thanks for replying.:smile:
What both of you have explained is exactly what was haunting me and been in my mind ( and that's why I qouted the above examples tosee if anyone could come up with the idea of an Impact Force) BUT the actual question...
@gmax : Good you pointed out my mistake regarding the train/tray example. So we will correct it.
And for the first example ( ire the bike one), I would say that ONLY consider it from Inertia point of view for a while, just forget the effect of friction and drag,(dont just bring them in...
We all must have come across the specification of ' Zero to Maximimum Speed' ie called Acceleration Time or 'Pick Up ' of the bike. I would call it the 'Response Time' for the Maximum Speed. It is the ('0 to 120/100 or so km/hr in 6 secs' ) or something similar.
This means that the bike would...
