How to calculate stopping force and stopping torque 1

[Startto]

I have a bundle of steel bars with each bar measuring length about 1.5m. Total weight of bundle is 650kg.If I fasten the steel bar bundle to a hydraulic motor in centre position of the bundle(.75m to each end) and rotate it with 800 Nm of torque.How to calculate the stopping force and stopping torque produced on sudden shutting down of the motor.

During sudden shutdown a sudden pressure hike upto 85 bar is witness in return flow.
where as,inlet is supplied with 22.9 L/min flow with 75 bar pressure.

also, hydtools, your equations assume that from t0 to t1, the motor would continue to accelerate indefinately? for example if t1 is infinity the motor speed would be infinity.

We know that a hydraulic pump only supply a finite amount of volumetric flow, so the equations dont work unless you are assuming the supply flow is infinite.

You are correct. I assumed the time period is short, the load just beginning to turn and then suddenly stopped. The OP seemed to indicate that that would be the case. Perhaps I misread.
