High strength steels are being used to reduce weight on cars.

explain why using a high strength steel would allow you to reduce the weight of a component?

pick a high strength steel and heat treatment for that steel and provide the steel's yield strength and elongation (or fracture strength)?

describe at least two concerns you would have when replacing regular steel with high strength steel?

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.
