Wimpy Radar Antenna! Grades 6-8.
Rushton, Erik; Ryan, Emily; Swift, Charles
In this activity, students reinforce an antenna tower made from foam insulation so that it can withstand a 480 N-cm bending moment (torque) and a 280 N-cm twisting moment (torque) with minimal deflection. One class period is used to discuss the problem, run the initial bending and torsion tests, and graph the results. The second class is used for design and construction of a sturdier tower and testing and graphing the results. This activity requires a 200-minute time period for completion. (Author/SOE)
