Which step in the engineering design process likely broke down in the following scenario? The Tacoma narrows project required a bridge to be build over the Colombia river. the engineers accounted for aesthetic design by building a light roadbed. Unfortunately, the cables were not designed to withstand high wind speeds, and the bridge collapsed

A. Brainstorm possible solutions
B. Conduct background information
C. Design and build a prototype
D. Test and resign a prototype

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
