Answer:
mg = 30.415 lbf
Explanation:
from figure body of size 3ft*2ft is tend to move down side
weight is divided into two component
vertical component = mgcos15 and
horizontal component = mg sin15
considering horizontal component equal to shear force
mgsin15 = \tau A
mgsin15 =\mu \frac{dv}{dh} A
mg =\frac{ \mu v A}{h*sin15}
=\frac{8.2*10^{-2}*0.2*3*2}{0.0125*sin15}
mg = 30.415 lbf
Answer:
I would say a level
Explanation:
A level is used as a horizontal reference line, which will tell if the building is leaning to one side, or if its up right. I may be wrong but this is the closest thing I can think of for this question.
THE ANSWER IS B Beaycs i like BExplanation:
Answer: C) Sump pit
Explanation:
Wastewater from the house is allowed to flow out of places such as the bathroom or the kitchen sink through a floor drain.
This floor drain is connected to a sump pit which is typically located at the lowest point in the house (lowest point in basement) so that water can flow into it easier.
When the wastewater is released from the floor drain, it will flow into the sump pit. This water is in turn removed from the pit by a sump pump.
