The city of St Louis in the United States has a monument known as the "Gateway Arch" which is pictured in Figure 1 below. You have been asked to help design a small-scale replica of this arch for Brisbane Figure 1 - Gateway Arch in St Louis, Missouri To simplify the design problem, you can assume that the arch follows a parabolic equation (and that the thickness of the arch is negligible). This equation that the arch follows will be...

3. This problem is to prove the foll owing in the precise fashion described in class: Let O R2 eopen and let/ : O → R have continuous partial derivatives of order three. If (zo,to) e o, )(0,0), fxr(ro, vo) < 0, and frr(ro, o)(ro, o)- ay(ro, Vo) 0, then f achieves a local maximum value at (zo. 5o) (that is, there exists 0 such that Br(o, vo) S O and (x, y) S f(xo, so) for all (x, y)...
Problem 1. An unknown material is characterized by e-80, Nr = 1, and o- 1000 (S/m). At each of the following frequencies, determine if the material may be considered a good conductor, a quasi-conductor, or a low-loss dielectric, and then calculate , B, 2. Hp, ne, and skin depth: (a) 60 Hz (10 pts) (b) 1 GHz (10 pts)
Problem 5 (20 Points) Member AC in the truss pictured below is heated at point C from the ambient temper- ature Tį to T2 > Tı). The following change in temperature in member AC results: AT(2) = 0 1-Ï), c=T2-T1. Note that AT(x) varies linearly from T2-T1 at x = 0 (point C) to 0 at x = L (point A). Members AB and AD remain at T1. All members of the truss have the same Young's modulus E, cross-sectional...
