A wheel of radius r is placed on ground


Asked by admin @ in Physics viewed by 388 People


A wheel of radius R is placed on ground and its contact point is P. if wheel starts rolling without slipping and completes half a revolution, find the displacement if point P. please justify the answer

Answered by admin @



Hi 
The revolution can be measured using formula 
Revolution = 2πr
Now if wheel covers one half revolution then it will be equal to 
= 2πr / 2
since π = 3.14
so
= 2(3.14) r/2
= 6.28r / 2  
or 3.14 r

We can find the Ф of rotation using 
Ф = s/ r
