Solving for impact force
Solving for impact force
(OP)
Hi all,
I have conducted impact tests of steel sphere against steel plate. I collected data of voltage generated by piezoelectric crystal of force sensor. This voltage is proporational to the displacement. Ok I have two data series(columns), first for time & displacement. In MATHCAD, how can I differentiate this displacement against time to get velocity & then acceleration. As data is in column format.
Thanking in advance.

a(n):=x(n+1)-2*x(n)+x(n-1)/(delta t)^2
We have provided to very simple ways of calculating the velocity and acceleration.
There are higher order interpolation methods.
