A 40 foot beam that weighs 125 pounds is supported at the two ends by walls. It also supports a 600 pound AC unit 5 feet from th
Dmitrij [34]

Answer:

A) 588 pounds

Explanation:

According to the given conditions, we assume the beam to be simply supported at the ends carrying a uniformly distributed load of 125 pounds per feet and a point load of 600 pounds acting at 5 feet from the right support.

Referring the schematic:

<u>Moment about any point will be zero in equilibrium condition. </u>

∴Take moment about point L

F_r\times 40=125\times 20+35\times 600

F_r=587.5 lb

If the temperature rises by 9. 9 degrees, what is the corresponding temperature increase in degrees celsius?
Yanka [14]

Main Answer:

Assume that the temperature rises by 9.9 F

Initial Temperatures will be C1, F1

Final temperatures will be C2, F1 + 9.9

The relation between celsius and fahrenheit temperature is as follows:

C = 5/9(F - 32)

Increase in temperature in celsius will be

C2 - C1 = F2 - F1

C2 - C1 = 5/9 ( F1 +9.9 -32) - 5/9 ( F1 -32)

C2 - C1 = 5/9 ( F1 +9.9 -32 - F1 +32)

C2 - C1 = 5/9 (9.9)

C2 - C1 = 5.5C

Explanation:

What is temperature?

Temperature is defined as the degree of coldness or hotness of an object or a substance. Generally, it is measured in various temperature scales. They are celsius, fahrenheit, kelvin.

3. If a pipe with flowing water has a cross-sectional area nine times greater at point 2 than at point 1, what would be the rela
shusha [124]

Answer:

The velocity of the flow at point 1 is nine times greater than the velocity at point 2.

Explanation:

We know that the same volume of water entering through point 1 must exit through point 2.

The volume of water per unit of time or the volumetric flow is defined by:

V_{flow}=v*A\\ where:\\V_{flow}= flow [m^3/s]\\v=velocity[m/s]\\A=area [m^2]

If  A_{2}=9*A_{1}  \\

therefore

v_{1} *A_{1} = v_{2} *A_{2} \\v_{1} *A_{1} = v_{2} *9A_{1} \\\\v_{1} = 9v_{2}  \\
