Answer: The engineering design process emphasizes open-ended problem solving and encourages students to learn from failure. This process nurtures students abilities to create innovative solutions to challenges in any subject! In addition to their involvement in design and development, many engineers work in testing, production, or maintenance. These engineers supervise production in factories, determine the causes of a component's failure, and test manufactured products to maintain quality.
Explanation:
Answer:
a.
b.
c. Work out put = 564 KJ/kg
d.
Explanation:
Given that
Heat in put = 1000 KJ/kg
Compression ratio,r = 8
Process 1-2
Process 2-3
We know that for air
We know that efficiency of otto cycle
Work out put = 564 KJ/kg
So
Answer:
Option A
Explanation:
Alloys are metal compounds with two or more metals or non metals to create new compounds that exhibit superior structural properties. Alloys have high level of hardness that resists deformation thereby making it less ductile compared to polymers. This is due to the varying difference in the chemical and physical characteristics of the constituent metals in the alloy.
