*4–68. the c83400-red-brass rod ab and 2014-t6- aluminum rod bc are joined at the collar b and fixed connected at their ends. if there is no load in the members when t1 = 50°f, determine the average normal stress in each member when t2 = 120°f. also, how far will the collar be displaced? the cross-sectional area of each member is 1.75 in2.

On a geologic map, if the contacts between sedimentary rock units form a bull’s-eye pattern of concentric circles, with the youngest unit in the center, the underlying structure is a(n)

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
