Hi Need some advice regarding my exhaust, I am building a dragbike. Info: Vtwin Engine 45degrees (Harley Shovelhead) I whant to build a 2-1 (both cylinder connected to one pipe) I´ve learned that the primary should be at same length (driveabilty and performance) , If I don't do this, what's...

((3.33*10-6)*(sin24.5))/2 ((3.33*10-6)*(sin24.5))/3 Red 690nm Blue 461nm True ?

No that was what i was thinking about, so I understand it now, its much easier to see it happened ;-) Thanx

Homework Statement A light hits a spektrometer perpendicular into a gitter with 300 slits/mm. You observes that a red and a blue line (in Visual light) coinciding. And the angle deflectionis 24.5°. What wavelenght have the red and the blue lines. No n is given. Homework Equations d*sinα=n*λ...

Thanks a lot sir! we will meet again ;-) best regards Fredrik

The Attempt at a Solution ω21r1=ω22r2 ω21/ω22=r2/r1 √(ω21/ω22)=√(r2/r1) ω1/ω2=√(r2/r1) I Think i got it right ?!

The Attempt at a Solution I am overseeing the weight i F. ω²r=ω²r ω²/ω²=r/r ω/ω=√r/r am I right ?? [/B]

or the potens rule axbx=(ab)x

Ohh sorry calculation fault I don't know the name in English (kvadreringsregler) (a+b)2 = a2+2ab+b2 this one is wrong! se next one..

agree (ωr)2/r = 2ω3r2

The Attempt at a Solution F = m·v2/r = (m* (ωr)2)/r ac =v2/r =(ωr)2/r

Homework Equations Friction force required to stay in circular orbit F = m·v2/r Maximum centripetal acceleration friction force can provide a at fly-off speed ac =v2/r on the right track?

Homework Statement There are two objects that are spinning on a plate and they fall off, and the physical reasoning is that the angular velocity (ω) has to meet the condition ω1/ω2=√r2/r1 ω1= angular velocity objekt 1 ω2= angular velocity objekt 2 r2= objet 2 position to the center of the...

I Think that the relation is V=ωr correct? (and the friktionskoefficient is the same for both the objects)

yes of course , sorry There are two objects that are spinning on a plate and they fall off, and the physical reasoning is that the angular velocity (ω) has to meet the condition ω1/ω2=√r2/r1 ω1= angular velocity objekt 1 ω2= angular velocity objekt 2 r2= objet 2 position to the center of the...
