need help with the next part of my lab, been stuck for days, please help with data!

Rotational Dynamics Experiment Data Studio m: To investigate a rotating system under the inuence of a constant torque, and to verify Newton's Second Law for rotating systems. Apparatus: Rotational Apparatus. smart pulley, pulley with rod, Dell Laptop computer. Science Workshop Interface, thread. Procedure: Part A Set up the apparatus as shown in the figure. without the ring, with platter pulleys on the bottom. Use the bubble level to level the apparatus. Rotational Apparatus Smart Pulley I f 5 a" 2 ' Object of known mass Connect the laptop and Science Workshop Interface to their power supplies and connect the interface to the computer. Plug the smart pulley into digital channel 1 on the interface box. Turn on the interface and the computer. Start Data Studio. There is no prepared experiment le you will construct your own using the procedure given here. Click on Digital Channel 1 Experiment Setup window. and a \"Choose sensor or instrument...\" window will open. Find the Smart Pulley item and select it. Mouse over the \"Displays" window in the lower left. and find the \"Graph\" icon. Click and drag the graph icon to the \"Velocity, Ch1\" icon in the \"Data" window. A graph window will appear. Attach about 1.5m of thread to the step pulley and wind it up on the smallest of the three step pulleys. Attach the weight holder to the other end of the thread by wrapping 4-5 turns around it. Add weights to a total of 459 including the hanger. Rotate the platter until the LED just lights. Click the START button, release the weight so it falls while the Smart Pulley monitors the motion of the platter. Just before the weight hits the oor or the thread runs out, click the Stop button to stop the timing. In the graph window click the \"Scale to Fit" button to adjust the x- and y-scales so that all data is visible. Now select the \"Fit" pull-down menu and select linear t. The slope of this line represents the acceleration of the hanging mass. If you have bad data at one or the other end of the run, you can left click and drag on the graph to highlight data for the linear t. Repeat this process using the same radius spindle and a hanging mass of 1009. Repeat this process using the largest spindle radius and a 1009 hanging mass. For each trial compute the experimental value of the moment of inertia of the platter. Part B: Make sure the spindle is on the bottom of the main platter and place the second platter on top. Repeat the above procedure using a hanging mass of 1009 and the largest spindle (one trial only) and again using the linear acceleration from the graph. calculate the total moment of inertia of the two platters. Repeat this procedure for one platter and the ring and calculate the combined moment of inertia. Repeat this procedure for one platter and the bar and calculate the combined moment of inertia. Compare the experimental values of | with the theoretical values calculated from known formulas. IV.
