The uniform, slender rod AB has mass m and length L. It is pinned to a fork (at point O), with this fork attached to a vertical shaft. The masses of the fork and shaft may be neglected, as well as any friction in the pinned joint. The cord keeps the rod AB at a constant angle while the shaft is brought up to speed. Once the shaft sustains a constant angular speed, the cord is cut. Show that the equations governing the ensuing motion are given by:.

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
