Answer:
Explanation:
Given that:
Torque T = 2300 lb - ft
Bending moment M = 1500 lb - ft
axial thrust P = 2500 lb
yield points for tension σY= 100 ksi
yield points for shear τY = 50 ksi
Using maximum-shear-stress theory

where;






where;






Let say :

Then :



According to trial and error;
c = 0.75057 in
Replacing c into equation (1)




The required diameter d = 2c
d = 1.50 in or 0.125 ft
Answer:
The overflow rate is 4.24×10^-4 m/s.
The detention time is 7069.5 s
Explanation:
Overflow rate is given as volumetric flow rate ÷ area
volumetric flow rate = 0.3 m^3/s
area = πd^2/4 = 3.142×30^2/4 = 706.95 m^2
Overflow rate = 0.3 m^3/s ÷ 706.95 m^2 = 4.24×10^-4 m/s
Detention time = volume ÷ volumetric flow rate
volume = area × depth = 706.95 m^2 × 3 m = 2120.85 m^3
Detention time = 2120.85 m^3 ÷ 0.3 m^3/s = 7069.5 s
Answer:
skyscrapers and bridges both have structural builds accounting for the influence of wind and they both cost big money
Explanation:
Answer:
None of these is correct.
Explanation:
The wave particle duality has to do with Louis de Broglie's proposition that matter could exist as waves or particles.
According to him, matter poseses an associated wavelength. Hence, a certain wavelength is traceable to the hydrogen atom.
This wavelength is the ratio of Plank's constant to the momentum of the hydrogen atom
Everything wrong with 2020 is WW3 that dump trump decided to start , Australia fires , Kobe passed away than Pop smoke :( corona virus got really big , quarantine started , riots & protesting started because of that dumb who’re racist cop ! Hope this helps
