Once a wheel is rolling, several factors inhibit its motion.
It means every thing is made out of Atoms and some things are element componds so elements are the "backbone" of the compounds.
The angle of bank needed, measured from the vertical is 86.6⁰.
<h3>
Banking angle of the circular path</h3>
The angle of bank needed, measured from the vertical is calculated as follows;
v = √(rg tanθ)
where;
- v is the speed = 1440 km/h = 400 m/s
- r is radius of the curve = 960 m
- g is acceleration due to gravity
- θ is the banking angle
400² = (960 x 9.8 x tanθ)
tanθ = 400²(960 x 9.8)
tanθ = 17
θ = arc tan(17)
θ = 86.6⁰
Thus, the angle of bank needed, measured from the vertical is 86.6⁰.
