Here is what I think about it all...
Pick up of a Cricket bat and adding a grip or weights to the handle
Ok you’ve added a grip or some sort of weight to the handle because the cricket bat you have bought picks up like a railway sleeper. The cricket bat feels better with regards to picking up but all of a sudden you’re getting bat vibration from the where the middle was.
The techie bit, only a little bit!
The point at which you get the least vibration from the bat is called the coefficient of percussion [COP]. I think I’ve discussed this before so take a look at another article for the infomation on this.
Hmmmm, by adding weight, e.g. an extra grip, you move the centre of mass or the balance point of the cricket bat towards the handle and this moves the COP [the point of least vibration]. That is because the coefficent of percussion is related to the total mass of the cricket bat, the balance point and the moment of inertia…..
So what does that mean?
The cricket bat picks up better but all of sudden the middle feels like it has shifted by about an inch all because of the extra weight at the handle end!
