  • The mechanics of belt friction revisited

    in the belt T = T(ϕ), the pressure p = p(ϕ), and the friction f=f(ϕ). The problem is thus statically indeterminate, unless the pull-force is sufficiently increased to pro-duce the state of impending gross slip of the belt. In the latter case, adopting the Amontons–Coulomb law of dry friction12, the local friction force is f = μp and the

  • newtonian mechanics - Motion of a box in a conveyor belt ...

    Put a pendulum in your box attached to the lid and set it swinging before you drop the box on the conveyor belt: The dynamic (kinetic) friction will then implicitly depend on time: $$ f_k(t) = mu_k N(t) $$. I am not aware of any dry friction models that are explicitly time dependent; that would be a very strange model of dry friction. I can't even take a wild stab at what could cause that.
