Motion of a box in a conveyor belt - Physics Stack Exchange

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.

belt sag and belt profile - bulk-online Forums

Jun 11, 2016· which can be derived from belt sag equations in DIN and CEMA. The point is, in deriving this equation for sag, belt curvature on rollers must be neglected (this way they will presumably be equal to idlers’ radius!!) and the result is a constant belt radius between rollers; which is in clear contrast with the cosine profile of the belt! any idea?

Mass balance - Wikipedia

Strictly speaking the above equation holds also for systems with chemical reactions if the terms in the balance equation are taken to refer to total mass, i.e. the sum of all the chemical species of the system. In the absence of a chemical reaction the amount of any chemical species flowing in and out will be the same; this gives rise to an equation for each species present in the system.
