Hello to all Mathcad professionnals
I need your help again.
I need to calculate a drive torque for a wheel climbing a ramp.
i can calculate this, but my worksheet is not elegant and is heavy 😥 (probably, i'a m using matchad programmation not correctly)
Here is now i do
The ramp is cylindrical profil
in first time
now, i dicotomize a ramp ( arc lenght)
In second time. At this step, this is a mechanical problem
I assume the ramp angle is simply a/2 .
In fact, the ramp (red line, on the picture) is the tangent equation at the circle. the first point where we calculate a tangent is calculate with polar coordinates from dicotomized values.
I think my result its Ok
but i want more 😁
I want calculate all Traction forces and all associated torques for all dicotomized value.
in one program ?
and i want to draw all result
at this moment i am lost, can you help me
thank

Thanks!
it's good !
C is Torque (Couple, in my language, because is Forces x lenght is a couple of values)
the red curve must be negative , because the wheel 1 ( blue curve) climb the ramp
and the wheel 2 ( red curve) go down the ramp
the force has left the wheel 1 at 22.5deg , even if it continues to climb, the torque decrease.
fabulous , i learn Mathcad slowly ... Thanks Werner 👍
