Answer 1

These are easily explained in the following images.

axis, the act Where tk 1/2 9 L. P 13 so, NO Reactive force will feel an the Hamms (b) centre of Percussion It is the point along the normal throoge Which the resultant of the effective forces In and It on a body, It is at a distance Ib from the centre of rotation. b= Koz P 20/3 For a straight body of straight lined It is at 24/3 from hinged point. The Reaction on the point ľ is zero is called centre of Percussion Its montant in industry in is used to apply the Force to minimise the vibration. joint. → Translational and rotational motion concels at the pivot. In hammer industry or some tools. It is made like that contre of Percusion lies on the read of Hammes and centre of suspension at the handle It where at a

Handle. » in the automobile, the contre of Percussion will located in the rear axle to avoid the Bumb on the in the front wheels. How to Determine It's co-ordinates and radius. OB= OB=0 torces, mass = m of Bar Ft is effective e/2 . ГВ A Force F is applied at point p such that b= Ko [b=distanca z? Moment of Force, about o M=Fxb= FXKZ Exkot = loxx is 7 where & is angular acceleration.
