I would like to know that which sensors arduino can support to study dynamics and static forces in moving mechanism .
Thank you
Actually all sensors.
Basically: strain gauges, also wrapped in scales or torquemeters.

i am trying to learn this algorathim , strain gauge with arduino .

the attached article and github site for reference
On your INA pins 6 and 7 are + IN and - IN which get connected to your bridge output. This is the data sheet for your INA. The data sheet gives examples. What exactly is your question?
Also your bridge reflects a pair of 1200 Ohm resistors? Normally bridges like this are all 120 Ohm or all 350 Ohm as pretty common. The idea being a balanced bridge.

The choice of a particular strain gauge depends greatly on the part and the place on the part you want to glue the strain gauge to measure the strain.
can i used Hx711 amplifier?
Yes, you can.
This would go much better if the project were well explained, in detail. We started with an INA125U and here we are at a HX711 module.
This is where I start looking at load cells. Again, please explain the project in detail. Exactly what data are you wanting to collect and once collected what do you want to do with it?
Arduino can support plenty of sensors. Depends on range you want or need as well as resolution you want or need?

Can't you calculate the stress depending on the load?
Placing strain gauges is artwork, you have to analyze the mechanism first, before you can know where to measure significant stress.
Also consider that strain gauges are highly temperature sensitive, more than strain. That's why usually more than one gauge becomes part of the bridge, for temperature compensation.

To my Mach-1 ME eyeball, the most interesting strains on that device look like they would be in places that are very awkward to apply a strain gauge to.
because some areas strain gauge hard to apply
yes indeed however that circuit is confusing
