A junction box contains two trade size 2 raceways on the left side, and two trade size 2 raceways on the top
What's the minimum distance from the left wall to the right wall?
Homework Answers
In straight pulls, conduit enters and leaves on opposite sides of the box. The depth of a box for a straight pull is determined by the size of the largest conduit and by space required by locknuts and bushings. On the other hand, the pull box length must be at least eight times the diameter of the largest conduit:
Minimum distance = 8 x 2
= 16

A box contains machinery that can rotate. The total mass of the box plus the machinery is m= 8 kg. A string wound around the machinery comes out through a small hole in the top of the box. Initially the box sits on the ground, and the machinery inside is not rotating (left side of the figure below). Then you pull upward on the string with a force of constant magnitude F= 133 N. At an instant when you have...

15) A uniform marble rolls down a symmetrical bowl, starting from rest at the top of the left side. The top of each side is a distance h above the bottom of the bowl. The left half of the bowl is rough enough to cause the marble to roll without slipping, but the right half has no friction because it is coated with oil.

A p-n junction is created by doping the right side of a piece of silicon with 1014 atoms/cm3 of phosphorus and the left side with 1018 atoms/cm3 of boron. Assume that the dopants are fully ionized, and assume the junction is at x = 0 with x+ pointed to the right. a) Plot by hand (roughly to scale) an energy band diagram of the junction and label EGAP, EC, EV, EF and EFi. Using the effective density of states, calculate...
