Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.

Problem No. 5 A rotating shaft carries four masses A, B, C and D rigidly attached to it; the centers of mass are at 30 mm, 36 mm, 39 mm and 33 mm respectively from the axis of rotation. The masses are 7.5 kg, mB, 5 kg and 4 kg respectively. The axial distance between A and B is 0.4 m, that between B and C is 0.5 m and the axial distance between C and D is H meters. The eccentricities of A and C are at 90° to one another. If the shaft is to be balanced completely, find mB, H and the angular positions of the masses B and D.
