The crew saw mud and gas pouring onto the floor of the rig. All the members of the crew instantly attempted to close the valve in the Blowout Preventer‚ which was intended to shut off the flow of high-pressure oil and gas from the well‚ but failed to seal the well because the drill pipe buckled for reasons that are still unknown. The crew could have redirected the flow of the mud and gas away from Deepwater Horizon and into the gulf‚ but instead they directed

Infrared Remote Control Switch ABSTRACT Now a days‚ everyone wants to control their appliance wirelessly (i.e. remote control). Here is a simple tested and inexpensive remote control switch utilizing reading available components. The project is designed to operate electrical loads using a TV remote. The remote transmits coded infrared data which is then received by a sensor interfaced to the control unit. The system operates electrical loads depending on the data transmitted from the TV remote. Operating

formulas relating the stresses in the walls of the cylinder and the gage pressure p in the fluid they contain. In the case of a cylindrical vessel of inside radius r and thickness t‚ we obtained the following expression for the hoop stress H and the longitudinal stress L. Mohr’s circle provides an alternative method‚ based on simple geometric considerations‚ for the analysis of the transformation of plane stress. Thin-walled pressure vessels provide an important application

The United States Should Switch to the Metric System One crucial‚ yet widely unnoticed issue plagues the United States of America today: the country simply faces a stubborn unwillingness to convert to the metric system. America spends millions of dollars on keeping the U.S. customary system in place. The refusal to convert hinders the country’s progress in the global economy. A conversion failure even sent a poor satellite hurtling towards destruction on the surface of Mars (Wheeler). The United
