Question

A team of engineers has been assigned the task of measuring the properties of a new turbine of a jet engine . You have previously determined that the moment of inertia of the turbine is 2.6 kg m2. The next job is to measure the frictional torque of the support. His plan is to run the turbine at a predetermined rotation speed , cutting power and measure the time it takes the turbine to reduce its rotational speed by 50 %. Your data are as follows : A team of engineers has been assigned the task of measuring the properties of a new turbine of a jet engine .

Explanation / Answer

We know that

Torque (T) =alpha*I

We have to find alpha from the given data , your data is not added to the probelm, if we consider the given data

then we can find torque =alpha*I
