Homework Statement
A disk with a 0.4 m radius starts from rest and is given an angular acceleration α = (10θ2/3)rad/s2 , where θ is in radians. Determine the magnitude of the normal (centripetal and tangential components of a point P on the rim of the disk when t = 4s.

α =...
For the purposes of clarification:
I did not initially give an example since the question I had did not pertain to the root of any question I had been given in particular, but was my own question in drawing FBDs and wondering where the force parallel had gone which I remembered from working with...
I am looking for where gravity is pulling the car down the bank (not that the car is moving down the bank or not). So does that mean that the x component of the normal force is really what I am looking for?
One example would be:
For a car traveling with speed v around a curve of radius r, determine a formula for the angle at which a road should be banked so that no friction is required.
In this case we are looking to derive the design angle. But how do we account for force parallel. Or is force...
Homework Statement
This is a conceptual issue which I am trying to understand:
When you are describing a vehicle traveling on a banked curve, force parallel (the force which is found to be parallel to the surface of the road pointing down the bank) is omitted from the FBD and the equations...
