Answer:
<em>d. floor spans exceed that which is economical with site-cast or hollow-core slabs and exceed 60 feet.</em>
<em></em>
Explanation:
<em>
Double tee slabs are prestressed concrete castings usually about 100 m to 150 m long</em>. <em>They are usually used in the construction industry in structures requiring a long floor span (or roof span) exceeding 60 feet in length, that is required to bear additional load (additional load carrying capability</em>). Double tee slabs are usually employed in construction because they shorten construction time. reduce congestion at the construction site, and also reduce construction cost.
<em>They are the required choice in construction when the cost of site casting or hollow-core slabs is no longer economical due to the length of the structure exceeding 60 feet.</em>
Answer:
shaft is not transform 100% power
Explanation:
given data
current = 10 amp
voltage = 110 v
torque = 10.2 Nm
rotating speed N = 1000 rpm
solution
we get here first power that is consume by motor is express as
power = current × voltage .........1
power = 10 × 110
power = 1100 W
and power that transmit by shaft is express as
power = T × ω
power = T ×
power = 10.2 ×
power = 1068.14 W
so we can say from above both power
shaft is not transform 100% power
Answer: C) Both Techs A and B
Explanation:
Technician A and Technician B are both very right. Using a spray bottle and water, the ignition wire test can be carried out using any of the methods described above. Or, by using a grounded test lead that is connected to a multimeter, you can also conduct the test for faulty ignition wires.
Answer:
Spheroidite < Pearlite < Bainite < Martensite
Explanation:
Given materials in the question :
Pearlite, martensite, bainite and spheroidite
Now,
the correct order of the increasing toughness out of the given materials is
Spheroidite < Pearlite < Bainite < Martensite
These all are the forms of steel formed by different heating and cooling processes.
