Rolling Friction
Asked by rivika | 19 Oct, 2009, 08:12: PM
Expert Answer

 

 

The force of rolling resistance can  be calculated by:

where

F is the rolling resistance force (shown in figure 1),
r is the wheel radius,
b is the rolling resistance coefficient or coefficient of rolling friction with dimension of length, and
Nf is the normal force, which is usuaaly equal to weight of the object. So above equation clarifies the relationship between rolling force and mass of body and radius of the body

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
