1. You have been asked to design a flexible pavement and the following daily traffic is expected for design: 6375 passenger cars with two 2-kip single axles, 375 18-wheel trucks with one 12-kip single axle and two 32-kip tandem axles, 225 triple-trailer trucks with one 18-kip single axle and six 36-kip tandem axles, and 525 single unit trucks with one 10-kip single axle and one 24-kip tandem axle. There are 3 lanes in the design direction (conservative design is to be used). Assuming a structural number of 5.0, determine the design-lane 18-kip ESALs for the pavement projected 15-year design life with the TSI of 2.5. [30 points]

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
