The space shuttle design team spent two years working with sketches and models before building the shuttle. Why were these steps important?
1.Sketches and models allowed for the design to be modified before investing huge amounts of time and money to build the actual shuttle.
2.Sketches and models allowed for many different astronauts to provide input on the design of the shuttle before investing money in the actual shuttle.
3.Sketches and models helped astronauts in their training program as they prepared for their missions.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
