In the context of inertia forces on rotating bodies, what assumption is made about the motion of each element?
In the context of inertia forces on rotating bodies, what assumption is made about the motion of each element?
- Each element moves in one plane, and all elements move in parallel planes (correct)
- Each element moves in multiple planes simultaneously
- The motion of each element is chaotic and unpredictable
- The motion of each element is independent of the others
What is the relationship between the angular velocity and acceleration, ω and α, in the context of inertia forces on rotating bodies?
What is the relationship between the angular velocity and acceleration, ω and α, in the context of inertia forces on rotating bodies?
- ω= α/t, α= θ/t
- ω= dα/dt, α= dθ/dt
- ω= dθ/dt, α= dω/dt (correct)
- ω= θ/t, α= ω/t
What is the Instantaneous Axis of Rotation assumption in the context of inertia forces on rotating bodies?
What is the Instantaneous Axis of Rotation assumption in the context of inertia forces on rotating bodies?
- The axis of rotation changes constantly
- Motion can be considered as a rotation about some instantaneous axis perpendicular to plane of symmetry of the body (correct)
- The axis of rotation is parallel to the plane of symmetry
- There is no specific axis of rotation
