Thanks For Watching.
In step no 6 why did you use rotor dia? You should use rotor radius I think.
bro how did u calculated Fd in step 1?
Further any formulas needed for regenerative braking system in e-baja
Wil the formula remain the dame to calculate the rotor torque in the case of wire actuated disc brake
Can these formulas be used to design a motorcycle brake disc and selecting a right MC kit?
clarify this calculations is completely used for e-baja braking system or not and also any implement needed for this please tell
in step no.6 , what are we supposed to take? ROTOR RADUS or ROTOR DIA?
I am designing rotor disc
If you know how to consider or calculate rotor diamentions like outer diameter, inner diameter, rotor thickness , hole diameter , rotor's thickness then let me know
Which master cylinder is used
can somebody please explain me how caliper clamping force is twice that of caliper piston force
For heat generation in disc while applying brake, that time total kinematic energy should be divide to no. Disc..
Why you didn't consider that?
This the formula of total kinematic energy is used for a single disc.
@@atvcalculations4539 but 3 or 4 discs stop the vehicle not single disc so don't we need to divide the energy
All the wheel are running with the same velocity so we don't need to divide energy we have to apply that coming energy entirely on one disc only.
bro how did u calculated Fd?
The data used in the video was the actulal data of the vehicle or random values were taken ?
Actual values
Why did you took mv= 210 * 9.81 in step (8)?? It's just mv=210kg , right??
bro gravity force
7. Something value will be in g which is way higher.
It's a correction
there is a serious mistake in the calculations, in step 8 you've taken weight instead of mass in the calculation of declaration, the values should be absurd after that but I guess it is just a typo and the value is not exactly included in the calculations
in step 7 from where did you get rt?
What are the measured values needed for calculation
in step 7, what is rt and its units bro
how to get effective radius of the rotor!!!
You have used effective radius of rotor 170 mm for torque calculation. ...
170 is dia. of rotor dude.
By mistakely that happened...sorry for inconvenience.....but don't worry formulas are absolutely correct 👍
@@atvcalculations4539 then waht will be the effective radius
@@atvcalculations4539 how to calculate the effective radius of rotor sir?
If we don't have the rotor dia...then how we calculate torque on rotor
How did you solve your query?
@@playtuber9239 first u have to calculate required torque by considering wheel radius after that u go for calculations of effective radius of disc. From the effective radius u can calculate outer radius and inner radius of disc and also generated torque.
@@harshadshrirame942 i have calculated the effective radius of the discs. Is it a problem if both of them are coming equal approximately? And how do you proceed for the outer and inner radii of the disc... is it from the thermal requirements?
@@playtuber9239 I didn't understand what u have to actually say.. Which are both effective radius coming equal? Explain it.
For outer and inner Dia - eff. Radius *2+ dia of caliper piston (for outer dia) and (D˄3-d˄3)/(D˄2-d˄2)*1/3 (for inner radius)
@@harshadshrirame942 i calculated the effective radius for front rotor and rear rotor. Both of them are coming to be approximately equal. I asked if it is okay or not that they are same.
In step no. 7 for inboard braking why the torque on all the wheels is same?
the frictional force acting on a single disc is that much that's why we haven't need to divide it we have to apply same value to all four wheels.
Torque will be same if dia of caliper is same everywhere.
But force on wheel will change as per no. Of disc assembled
The brake torque which I'm getting by using your formula is quite high as 700Nm, is it right ?
Don't worry it will be correct if you are doing it step by step as per the given instructions 👍
@@atvcalculations4539 Thanks 🙂
It is applicable for e-baja vehicle or not
Yes it is applicable
Isn't there a mistake in this video. You never checked what is the maximum amount of force that the tyres can apply during braking.
Can you provide that journal link....
Plz
hey did u have any journal regarding calculations pls share with me at 62vedant@gmail.com
Really Helpful
Thanks
All values measured from meters
Ur dividing it with weight and ur saying we have to divide it with mass....in declaration step...🙄🙄🙄
bro how did u calculate fd?
