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 m^2. 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:

Rotatin (rpm) Time (s)

1500 19

1800 22

2100 25

2400 30

2700 34

Make an appropriate graph of the data and the slope of the best fit, determine the frictional torque.

Explanation / Answer

finding difficulty to upload the graph.

angular acceleration = (1800-1500)/(22-19)= 100 rpm/s= 10.46 rad/s^2

torque= moment of inertia x angular acceleration= 2.6 x 10.46= 27.22 N.m
