A house will be built on half acre lots $(21,780f{t}^2)$ and the model is scaled down to fit on

a $1-$meter board $(10\mathrm{.}76$ ft$2).$ Estimate the scale ratio for a house model with $2,000$ sq ft

home $(50ft40ft)$ will take up about $1f{t}^2$ of the board $(14$ in x $10\mathrm{.}3in).$ If you want to

keep the same scale as the horizonal scale, what would be the scale for the height of a

building with $14ft$ height?

A house can sustain damage from strong winds at wind speeds of roughly $40-60$ mph

$(64-96k\frac{m}{h}).$ Moderate damage occurs at $60-80mph(96-128k\frac{m}{h}).$ Severe damage,

including considerable wall and roof damage, can happen at speeds of $80$ to $100mph$

$(128$ to $160k\frac{m}{h}.$ According to a report by FEMA, new wood$-$frame houses constructed

according to building codes perform well structurally, in winds up to $150mph.$ Following

the FEMA report, what is the maximum velocity to test the model without any damage to

the house model?

Prototype:

The aerodynamic drag force on the model house is measured with a drag balance. Several

drag readings are recorded, and the average drag force on the model is $21\mathrm{.}2lbf.$ Predict

the aerodynamic drag force on the prototype at the estimated maximum velocity.A house will be built on half acre lots $(21,780$ ft$2$
