Which step in the engineering design process most likely broke down in the following scenario? The Tacoma Narrows project required a bridge to be built over the Columbia River. The engineers accounted for
aesthetic design by bullding a light roadbed. Unfortunately, the cables were not designed to withstand high wind
speeds, and the bridge collapsed.
brainstorm possible solutions
conduct background research
design and build a prototype
test and redesign a prototype

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.

Fluids at rest possess no flow energy. a)- true b)- false

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
