2. Question 2 [43] A shaft is rotating at a uniform speed with four masses mi, m2, m3, m4 of magnitudes 150kg, 225kg, 180kg, 195kg respectively. The masses are rotating in the same plane, and the corresponding radii of rotation are 200mm, 150mm, 250mm, 300mm. The angles made by these masses with respect to horizontal are 0°, 45°, 120°, 255º respectively. 2.1. Find the magnitude and position of balance mass by drawing the Angular Position diagram and Vector diagram. The balance mass radius of rotation is 200mm. [24] 2.2. Use the Analytical method to determine the magnitude and position of the balance mass, placing the mass-radius of rotation at 200mm. [16] 2.3. Is there a difference between the two answers? Discuss your reasoning. [3]
