I've been looking over precedents for a design project and I noticed that the most commonly used systems are either steel or reinforced concrete structural systems. Is it possible for a steel structural system to be connected to a reinforced concrete structural system? If so, how does it work...

**Book is called Building Science for a Cold Climate

Step 1: Values are from textbook 'Building for a Cold Climate' Mbrick = 46 ng/s*Pa*m^2 Mgypsum = 2870 ng/s*Pa*m^2 (for 9.5mm) took the above value and used ratios to determine permeance for 10mm Gypsum board (2870/9.5 = X/10) Mgypsum (new value) = 3021.05 ng/s*Pa*m^2 Step 2...

Would that mean something like this? Δx/L = λ/d Δx = Lλ/d

Homework Statement Light of wavelenghs 4.80x10^2 nm and 632nm passes through two slits 0.52 mm apart. How far apart are the second-order fringes on a screen 1.6m away? λ₁ = 4.80x10^2 nm = 4.80x10^-7m λ₂ = 6.32x10^-7m d = 0.52mm = 5.2x10^-4m n = 2 L = 1.6 Homework Equations (Maxima/Bright)...
