A cylindrical bar of metal having a diameter of 20.9 mm and a length of 205 mm is deformed elastically in tension with a force o

f 45200 N. Given that the elastic modulus and Poisson's ratio of the metal are 68.8 GPa and 0.32, respectively, determine the following: (a) The amount by which this specimen will elongate in the direction of the applied stress. (b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Answer:

a. 1.91 b.  -8.13 mm

Explanation:

Modulus =stress/strain; calculating stress =F/A, hence determine the strain

Poisson's ratio =(change in diameter/diameter)/strain

Which feature should a system administrator use to facilitate them? When working on opportunities, sales representatives at Univ
il63 [147K]

The correct answers are B & C; Chatter Groups and Similar opportunities.

Further Explanation:

Sales representatives can use chatter groups and other similar opportunities to their advantage. This can help them to understand and manage their products that are in direct competition with competitors.

A chatter group can be used to share ideas both privately and publicly. These groups can have more than 30,000 people or just 3 people, it depends on how many are interested in the topic or product. The groups can be made unlisted and by invite only and then you can see with whom you are talking to. Nonmembers can view anything written in the public and archived groups. This is a great way to see how your peers are doing with their product.

While driving down the highway, your car must overcome the forces of friction and air resistance in order to keep the car moving
ElenaW [278]

Answer:

Efficiency of the engine equals 20%

Explanation:

We know that when the car moves it must do work against the resisting forces to keep moving and this work is spend as energy by the engine to keep the car moving.

we know that

Work=Force\times Displacement

Thus to keep the car moving for 100,000 meters the theoretical work that requires to be done equals  

Work=560N\times 100,000m=56\times 10^{6}Joules

Now the actual energy spend by the car equals the energy spend by burning 2.8 gallons of gasoline.

Thus the energy produced by burning 2.8 gallons of gasoline equals

2.8\times 100\times 10^{6}=280\times 10^{6}Joules

Thus the efficiency is calculated as

\eta =\frac{56\times 10^{6}}{280\times 10^{6}}\times 100\\\\\therefore \eta =20percent

Water and other liquids, known as fluids, have unique properties because they are materials that flow.
koban [17]

Answer:

True

Explanation:

liquids are fluid, able to flow and take any shape. this occurs due to the weak intermolecular bonding that allows the molecules to slide past each other freely. as a result of being fluid, liquids exhibit many interesting properties that solids do not, including capillary action and diffusion. liquids, like gases, undergo diffusion when mixed.
