Question 5: This question relates to unbalanced shafts. A shaft is supported in bearings A and B 1500 mm apart. It carries three masses, my, mz and mg with respective eccentricities rī, r, and rz. The location of each disk/ mass from bearing A is lily and lz as given in the datasheet. Figure 5, represent the location and angle of the masses on each disk. a) Determine the dynamic forces at A and B when the system revolves at 150 rev/min. b) Determine the two counter masses to balance the shaft, if it is located at a 200 mm radius and one balancing mass is revolving in planes midway of mass 1 and 2 and the other balancing mass is revolving in planes midway of mass 2 and 3. (15 marks) m; ma a m Space diagram Figure 5.
values for this question: m1(kg)= 1.3 m2(kg)= 0.7 m3(kg)= 1.7 r1(mm)= 9.0 r2(mm)= 4.0 r3(mm)= 4.00 L1(mm)= 300.0 L2(mm)= 600.0 L3(mm)= 900.0
For all cases please use the angular positions as: 01 = 90°, 02 90°, 02 = 180°, 03 = 225°,
