ENGINEERING DESIGN END SEMESTER examination


1. provide an approximate preliminary statement for bullet proof jacket. What Preliminary investigation
may be needed to set specifications for such a jacket?

2. There are many metrics which are involved in trade offs for different products. 1 example is Power vs Noise. Many Products that have engines fall into this category. More the power, more is the noise usually. We have to trade off ranging from noise and power to find an optimum design. Write two other pair of metrics which exhibit such trade-offs

3. define the role of prototypes before launching a new product in market.

4. What do you mean by a) ergonomics b) Design Tree

5. Draw the diagram for braking system of a bike having brake levers, break cables and break shoes.
If the reliabilty of the braking system is 0.9 compute the total reliability of the braking system of the bike.
