Engineering Preparedness for Disaster Mitigation September 15th is celebrated every yea in India as "ENGINEERS DAY" to commemorate the birthday of the legendary engineers Sir Mokshagundam Visvesvaraya .Sir Visvesvaraya, an eminent Indian engineer and statesman was born in a remote village of Karnataka, the sate that is incidentally now the Hi-tech State of the country. Due to his outstanding contribution to the society, Government of India conferred " Bharat Rathna " on this legend in the year 1955. He was also called the precursor of economic planning in India. his learned discourse on economic planning in India, planned Economy for India and reconstructing India, was the first available document on the planning effort of the country and it is still held as the parent source matter for economic planners. A theme of national importance is chosen every year by the council of the institution and deliberated at its various State/local Centers to educate the engineeri

Double Hooke's Type CV Joint One method of obtaining very near constant velocity characteristics is to position two Hooke's joints back to back so that their yoke arms remain in line with one another (Fig. 26.12).  Fig. 26.12. Double Hooke's type constant velocity joint. After assembly, both pairs of outer yoke arms must be at right angles to the arms of the central double yoke member. This double joint combination can be considered in two stages. The first stage hinges the drive yoke and driven central double yoke together, and the second stage links the central double yoke (now drive member) to the driven final output yoke. Consequently, the second stage drive half of the central double yoke is placed a quarter of a revolution out of phase with the first stage drive yoke (Fig. 26.13). Fig. 26.13. Double Hooke's type joint shown in two positions 90 degrees out of phase. Therefore, if the input and output shafts are inclined to each other and the first stage driven cent
