second floor bridge‚ with the third floor walkway set off to the side several meters away from the other two. Construction difficulties led to a flawed design change that doubled the load on the connection between the fourth floor walkway support beams and the tie rods carrying the weight of both walkways. This new design could barely handle the dead load weight of the structure itself‚ much less the weight of the spectators standing on it. The connection failed and both walkways crashed one on top

If there is one thing that everyone loves to do‚ and needs to do‚ it’s eat. When people worry about what they are eating‚ they worry about how many calories are in their food‚ if there’s glucose in it‚ or something else along those lines‚ but what consumers generally think about when they eat is how much radiation has been pumped into their food prior. Yes that’s right‚ many foods that you eat are treated with different forms of radiation. Food irradiation is the process of treating food with ionizing

proximity switches are equipped with temperature sensors and a compensation circuit‚ in order to be able to compensate for changes in operating distance caused by temperature fluctuations. The ultrasonic sensor can work in diffuse‚ reflex or thru-beam mode. Thru-Beam: In this case the emitter and detector are 2 separate units. The emitter emits the light which is detected by the detector. A target is detected when it passes in-between the emitter and detector. Diffuse Reflective: In this case the emitter

A medical field is a place full of diverse opportunities. Opportunities such as surgery‚ medicine treatments‚ and multiple therapy options. Radiation therapy has impacted many people’s lives just in the last few years. Cancer patients especially‚ have been given another chance at life through a few treatment rounds. In the past to remove cancerous tumors and small masses‚ surgery was the only option to improve those patients lives; with advances in technology and medicine‚ radiation therapy has

EARTHQUAKE An earthquake (also known as a tremor‚ temblor or seismic activity) is the result of a sudden release of energy in the earth’s crust that creates SEISMIC WAVES. Earthquakes are measured with a seismometer; a device which also records is known as a seismograph. SEISMIC DEFORMATION When an earthquake fault ruptures‚ it causes two types of deformation: static; and dynamic. Static deformation is the permanent displacement of the ground due to the event. The earthquake cycle progresses
