[Ans. 6.12 kg: 8.7 N-m] L 2. 3. 4. 5. 1. 2. 5. DO YOU KNOW? Why is balancing of rotating parts necessary for high speed engines? Explain clearly the terms "static balancing' and 'dynamic balancing'. State the necessary conditions to achieve them. Discuss how a single revolving mass is balanced by two masses revolving in different planes. Chapter 21: Balancing of Rotating Masses .857 Explain the method of balancing of different masses revolving in the same plane. How the different masses rotating in different planes are balanced? OBJECTIVE TYPE QUESTIONS The balancing of rotating and reciprocating parts of an engine is necessary when it runs at (a) slow speed (b) medium speed (c) high speed A disturbing mass, attached to a rotating shaft may be balanced by a single mass m, attached in the same plane of rotation as that of my such that (a) (b) F For static…arrow_forwardProvide a real-world usage example of the following: Straightness Circularity Parallelism What specific tools, jigs, and other devices are used to control the examples you provided?arrow_forward
- 856 Theory of Machines 5. A shaft carries five masses A, B, C, D and E which revolve at the same radius in planes which are equidistant from one another. The magnitude of the masses in planes A, C and D are 50 kg, 40 kg and 80 kg respectively. The angle between A and C is 90° and that between C and D is 135° Determine the magnitude of the masses in planes B and E and their positions to put the shaft in complete rotating balance. [Ans. 12 kg, 15 kg; 130° and 24° from mass A in anticlockwise direction]arrow_forward2. 3. 4. clockwise from Four masses A, B, C and D revolve at equal radii and are equally spaced along a shaft. The mass B is 7 kg and the radii of C and D make angles of 90° and 240° respectively with the radius of B. Find the magnitude of the masses A, C and D and the angular position of A so that the system may be completely balanced. [Ans. 5 kg: 6 kg; 4.67 kg; 205° from mass B in anticlockwise direction] A rotating shaft carries four masses A, B, C and D which are radially attached to it. The mass centres are 30 mm, 38 mm, 40 mm and 35 mm respectively from the axis of rotation. The masses A, C and D are 7.5 kg. 5 kg and 4 kg respectively. The axial distances between the planes of rotation of A and B is 400 mm and between B and C is 500 mm. The masses A and C are at right angles to each other. Find for a complete balance, 1. the angles between the masses B and D from mass A, 2. the axial distance between the planes of rotation of C and D. 3. the magnitude of mass B.
