1.	In the question number 82, the maximum permissible speed to avoid slipping is
Answer» `18.6"MS"^(-1)` `28.6"ms"^(-1)` `38.6"ms"^(-1)` `48.6"ms"^(-1)` Solution :The MAXIMUM PERMISSIBLE speed is given by `V("max")=sqrt((Rg+(mu+tan THETA))/(1-mutantheta))=sqrt((300xx10xx(0.2+0.27))/(1-0.2xx0.27))` `=38.6ms ^(-1)`
