Draw the shear and moment diagrams for the shaft, and determine its required diameter to the nearest kin. if u allow = 30 ksi and r allow = 15 ksi. The journal bearings at A and C exert only vertical reactions on the shaft. Take p = 6 kip.
Chapter 1 Who is 1. Wolmar Fellenius He’s the port engineer in Sweden, a professor at the royal institute of technology in stockhom and the chairman of geotechnical commission of the Swedish state railways. He conducted the first large scale geotechnical studies and developed exploration, sampling, testing and analysis techniques. 2. Karl Terzaghi Also known as the father of soil mechanics. In 1916, he began his research on the behavior of soils, including the studies of piping failures in sand beneath sand and settlement clays 3. Ralph Peck He developed the observational method and applied this approach to solving engineering problems. With the knowledge gained by terzaghi, he studied the areas of strength in soft clays, earth pressure and tunnel lighting. What are the branches of Civil engineering 1. Structure 2. Waste water 3.
