Explain whether the benefits outweigh the weaknesses of the dam described in the following scenario and provide an argument in favor of or against the project. Situation: Farmers in a small South American country have to cope with the spring Amazon River floods. They would like the government to build a dam that would control flooding and provide hydroelectricity. However, they are concerned about the effects it would have on the ecosystem, possibly causing severe erosion and impacting species survival.

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.
