Question

Review Your engineering team has been assigned the task of measuring the properties of a new jet-engine turbine. You've previously determined that the turbine's moment of inertia is 26 kg m. The next job is to measure the frictional torque of the bearings. Your plan is to run the turbine up to several different Initial predetermined rotation speeds, w, cut the power, and time how long it takes the turbine to reduce its rotation speed by 50% in each case. Your data are as- Part A You want to determine the frictional torque of the engine's bearings by graphing the data. Select the appropriahe variables to graph on each axis that will produce a straight-line graph with a slope that is related to the frictional torque. Sort all variables Into the appropriate bins follows: View Available Hintls) Rotation, wn (rpm) Time, t (s) 1500 19 Reset Help 1800 22 2100 25 2400 30 Horizontal axds Vertical axis Not used 2700 34 Submit

Answer 1

plot 't' on the vertical axis and ' w_i ' on the horizontal axis.

Reason - ' t ' is a dependent variable on ' w_i '
