Answer:
We choose PTFE
Explanation:
Attached are the modulus density and modulus strength chart.
Due to its young modulus, the density is near 0.5 GPa, as seen in the chart and support water gliding. The PTFE density is between 1 and 10 Mg / cubic meter (see module and chart of density), and the resistance is between 10 and 100 Mpa (see module and chart of strength). Therefore, the finest ploymer will be PTFE that meets the requirements.
Answer:
Change in kinetic energy=-513.652 KJ
Change in potential energy=431.64KJ
Explanation:
We are given that
Mass of an automobile , m=1100 kg
Initial speed, u=110 km/h=
Where 
Height , 
Final speed, v=0
Change in kinetic energy,
Where 1 KJ=1000 J
Change in potential energy,
Initially height, h1=0
Using the formula
Answer:
(c) an acme tool gage
Explanation:
with the help of an acme tool we measure the pitch of a screw thread it is used as reference for finding the pitch of the thread it is also called an inspection tool is aligned to work with an acme tool gage it is also used for gage the internal and external threaded product. it is also used for grinding and setting tools it is mainly work 29° thread angle
There are now six major branches of engineering: Mechanical, Chemical, Civil, Electrical, Management, and Geotechnical, and literally hundreds of different subcategories of engineering under each branch.
