What is the equation for the expansion of length when the support is allowed to expand freely?

The equation for the expansion of length when the support is allowed to expand freely is given by: $δT = α∆TL$, where δT is the temperature strain, α is the coefficient of thermal expansion, ∆T is the change in temperature, and L is the original length.

What is the equation for the stress and strains when supports are fixed?

The equation for the stress and strains when supports are fixed is given by: $stress = α∆T*E$, where stress is the stress produced, α is the coefficient of thermal expansion, ∆T is the change in temperature, and E is the modulus of elasticity.

What is the equation for actual expansion when the support yields by δ?

The equation for actual expansion when the support yields by δ is given by: $Actual expansion= Expansion due to rise in temperature - δ$

What is the equation for actual strain when the support yields by δ?

The equation for actual strain when the support yields by δ is given by: $Actual strain = \frac{Actual expansion}{Original length} = (α∆TL−δ)$ Signup and view all the answers

What is the equation for actual stress when the support yields by δ?

The equation for actual stress when the support yields by δ is given by: $Actual stress = \frac{L (α∆TL−δ)}{L} * E = (α∆TL−δ) * E$ Signup and view all the answers

What was the first mosque built by Muhammad and when?

The first mosque was a structure built by Muhammad in Medina in 622, right after his Hijrah (migration) from Mecca, which corresponds to the site of the present-day Mosque of the Prophet (al-Masjid anNabawi). Signup and view all the answers

How did the mosque evolve over time in the 7th and 8th centuries?

Over the rest of the 7th century and in the 8th century, the mosque was repeatedly expanded to include a large flat-roofed prayer hall supported by columns (a hypostyle hall) with a central courtyard, becoming one of the main models for the early mosques built elsewhere.
