Thermoset vs Thermoplastic Torch Experiment
Просмотров 2,8 тыс.Год назад
Polymers are either, (a) thermoplastics or (b) thermosets (a) Thermosets: Thermosets are thermally SET. They are liquid at room temperature before curing and after the curing process which can be through heat, radiation, pressure or cross linking, they become irreversibly hardened. The curing process is a chemical process which is not reversible, and the thermosets cannot return to their liquid...

great vid
Thank you! I am glad you found it helpful. Which university are you visiting from?
In the previous video, you used a fixed beam with UDL to calculate the equivalent load for an evenly distributed load. My question is, how does this work for determining the equivalent load for the second element of this problem?
You put it in the matrix form with all elements, all you need to know is what reactions you have at each support, if it is fixed you will have a moment and for pinned supports, you set zero for the moment value
Thanks for video, Why is the equivalent load calculated on the fixed beam case always? Why not in the simply supported beam?
That is the harder case as there are moments at the two end involved make the system statically undermined, the simply supported case is an easier system where reaction forces can be determined using equilibrium equations
Do professors gets extra pay when they help phd student? Or get pay for writing papers?
Great questions! Not normally, that is part of the job! Unless you have an accepted grant, then you can pay yourself summer salary or supplement your academic year salary up to 20%.
thank you for sharing your knowledge
You are welcome! I am glad you found it helpful
thank you so much
You're welcome! I am glad you found it helpful
Thank you so much! I was stuck on this problem and you were the only one able to help me.
You are welcome
I have a question about compensating the toe region. A continuation of the linear part should be generated in order to find the corrected zero strain point. Am I right? after that, should stress start from zero too? after this procedure, at the beginning, before the linear part, still there will be an inclined part. Is it right?
At the zero strain, the force is not necessarily zero due to tightening the grip! Stress-strain curve is not a good indication of initial conditions and it is hard to find the force at zero strain unless you read the machine recording at the time of experimentation! Extrapolation of stress strain curve will give you inaccurate beginning point. You can shift the stress-strain curve to give you more reasonable stress and strain values but do not extend it beyond its limit of recording
Dear, from what book do you get those exercises? Greetings from Peru
It is Hibbler book
Thank you so much ❤
You're welcome 😊
Thanks very much for this it has really helped me to understand this ❤❤❤
You are welcome! I am glad you found it helpful
Sir why is it negative when it is moving the beam clockwise?
That’s our agreed convention to call a clockwise moment negative and counter clockwise moment positive, but in general if you use the right hand rule, a clock wise motion is towards negative Z which is the axes perpendicular to the page and counter clock wise would be towards positive z
How did you get 300N/m cause after using similar triangles that is supposed to be 200N/m
Thanks sir
You are welcome! I am glad you found it helpful
What is the name of Book?
Dynamics-Hibbeler-14th-edition-book
It’s Hibbler
Thank yoU!
You're welcome!
Excuse me, I'd like to ask, what do we do if the length of point C from either point A or B is unknown?
Then you need to have other information available
isnt L 0.6-0.3cos45?
wouldn't the final angle be 120 since the measurement is taken from outside of the triangle
Sir how to learn fluid mechanics in easy way any book ?
reminds me of that tragedy
What tragedy? Did you fail statics?
Which book
Hibbler
Ax =0 thats seems untrue
In practice, there are forces, but in theory if only external vertical forces are applied and in absence of external horizontal forces, there is no reaction forces to oppose any forces
Very nice example. Could you tell me from which book is it?
Hibbler
How did you find Fea and Feb, you never finished those equations
if you analyse the joint A, you can notice an Y force (as well as on joint B). then, you do: Mo= 6 times YB + 900 times 4 + 600 times 8. YB= -1400 N ΣFY= YA+YB= 0 so YA= 1400N afterwards, we can find the angle of the ABE triangle: 4/3 (half of the base)= 1.333333 1.333= tg 53.13 if Fea= Ya times sin 53.13 then Fea equals 1750N you can find Feb easily after that.
Nice work
Thanks
Good stuff
Glad you enjoyed
Tnx a lot dr ❤️
You are welcome
why is 2/3?
The centroid of a triangle is 2/3 from the edge of the triangle or 1/3 from the base! It can be proven but normally memorized as a rule
Can you provide matlab file?
I don’t think I can attach them here. Which school do you go to?
How did you figure out the 100 for the triangle when you cut the beam?
Using similarities of triangles, before it was cut the bigger triangle had 200N/m, after it was cut the smaller triangle was exactly half of the bigger one, finding the ratio(i.e 200:x=6:3) , x= 100. Note that 6 and 3 are just the base distances of a bigger and smaller triangles respectively.
Thank you@@godfreymutale4876
how do you determine the distance from Fr1 and Fr2 from b ? i dont really get this part
Good question! For a rectangle, it is in the middle and for a triangular load, the resultant force is acting 1/3 of the base from the right angle of the triangle.

Are you sure its 115.5N? I got 113N and that's what the answer key in my book said
