# Angular-acceleration sentence example

angular-acceleration

- If dw/dt is the angular acceleration of the link, dw/dt X CB is the tangential acceleration of the point B about the point C. Generally this tangential acceleration is unknown in magnitude, and it becomes part of the problem to find it.
- To find the angular acceleration A, draw kI, bt respectively parallel to and at right angles to the link KB.
- Then tb represents the angular acceleration of the point B relatively to the point K and hence tb/KB is the value of A, the angular acceleration of the link.
