You must supply a 100 MW load. You can buy a five year contract for 100 MW of power 24 hours a day for $130M. (You pay the $130M up front and can consume up to 100 MW per hour. Any power you do not use is lost. But, assume you will use all of it.) Alternatively, you can buy a 100 MW generator with a 30 year life for $70M and pay fuel and maintenance costs of $15/MWh. Analyze costs using a 4% real interest rate and determine which is the cheaper alternative.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

On a average work day more than work place firs are reorted

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.
