Normal Force Calculator Flat and Inclined Surface

01/06/2020  To find out how to calculate normal force with friction, use the friction calculator. For objects on a flat surface, the normal force is counter to the objects weight. (Don't confuse it with mass! Weight is the same as gravitational force.) That is only the case when there is no outside force acting on the object, or, if there is, the outside force is parallel to the surface. Let's see what ...

How to find the transfer function of a system – x

For a dynamic system with an input u(t) and an output y(t), the transfer function H(s) is the ratio between the complex representation (s variable) of the output Y(s) and input U(s). For a better understanding we are going to have a look at two example, two dynamic systems, for which we are going to find (determine) their transfer functions.
