This is suitable for conducting experiments on static balancing and dynamic balancing with different weights. This consists of rectangular frame of steel perfectly balance with four different blocks. A protractor scale of the disc is provided to reach exact angular position of each weight to be measured. A linear scale provided below the frame provides the measurement of each weight along the shaft. The unit is hanging from a rigid steel frame through chain for dynamic balancing and can be fixed rigidly for static balancing.specified in the IS 2386 (Part I).
