In this math activity, students conduct a strength test using modeling clay, creating their own stress vs. strain graphs, which they compare to typical steel and concrete graphs. They learn the difference between brittle and ductile materials and how understanding the strength of materials, especially steel and concrete, is important for engineers who design bridges and structures.

Students take a hands-on look at the design of bridge piers (columns). First they brainstorm types of loads that might affect a Colorado bridge. Then they determine the maximum possible load for that scenario, and calculate the cross-sectional area of a column designed to support that load. Choosing from clay, foam or marshmallows, they create model columns and test their calculations.

For ppt 1: IntroductionWireless Sensor Networks are densely deployed low cost, low processing power, less memory and limited energy resource networks.In WSN, the nodes are called sensors which sense the data like temperature, humidity, noise or sound, pressure, soil variety, movements of objects, stress levels, detection of objects around etc. from the surrounding and send this information to the base station (sink) for further analysis and decision making. For ppt 2: Introduction •Three main components of Wireless Sensor Networks are 1) Sensor nodes 2) Cluster Head 3) Base Station•Increased application area of WSN.•Hence, increase in network traffic, increase in storage, increase in transmission power.
