Five (5) uniform discs of mass 5 kg each are fitted onto a shaft which is rotating at 3,000 rpm constantly and supported by two (2) bearings P and Q as shown in Figure Q1. The system is initially totally balanced. If a few modifications are carried out as following:- Disc B: Removal of 0.2 kg at radius 0.01 m and position 240° Addition of 0.1 kg at radius 0.02 m and position 150° Disc D: Calculate the following:- The dynamic force acting on bearings P and Q. The mass mc and mg to be added at disks C and E respectively to be positioned at radius 0.02 m, and their respective angles to balance the system. а. b. 0.1 m 0.1 m 0.1 m 0.1 m 0.1 m 0.1 m 90° 180° 0° P 270° C E Figure Q1 -図区。
