Answer:
Explanation:
Floor Load:
Lo= 50psf
At= 25x25 = 625 square feet
= 13.1psf
%reduction= 13.1/50 = 26%
Fr= 3[(13.1psf)(25ft)(25ft)+(20psf)(25ft)(25ft)]= 62k
Answer: D
Find the answer in the explanation
Explanation:
Elastic solid will obey Hooke's law which state that the force applied is proportional to the extension provided the elastic limit is not exceeded.
Examples of Newtonian fluid are water, glycerol, honey and all organic solvents
When comparing solids to fluids, the below statement is true
We can therefore conclude that
For elastic solids, stress is linearly related to strain, and for Newtonian fluids, stress is linearly related to strain rate
Answer:
long duct: 1.0 and 0.424
Hemisphere 1.0 ; 0.125; 0.5
Explanation:
For a long duct:
By inspection, 
Calculating by reciprocity, 
Hemisphere:
By reciprocity gives = 0.125
using the summation rule: 
However, because this is a hemisphere, the value will be= 0.5 * 1
= 0.5
Answer:
Ψ = 10(y^2) + c
<em><u>y = 1.067m</u></em>
Explanation:
since the flow is one dimensional in positive X direction, the only velocity component is in X, which is denoted by u
while u is a function of y
we find the u in terms of y; u varies linearly wih y
we use similiraty to find the relation
32/1.6 =<em>u/y</em>
<em><u>u = 20y</u></em>
<em><u>Ψ = ∫20ydy</u></em>
<em><u>Ψ = 10(y^2) + c</u></em>
<em><u>(b)</u></em>
<em><u>the flow is half below y = 1.6*(2/3)=1.067 m</u></em>
<em><u>this is because at two third of the height of a triangle lies the centroid of triangle. since the velocity profile forms a right angled triangle , its height is 1.6 m . the flow is halved at y = 1.067m</u></em>
