Eng 2116 Engineer Egg Drop Paper Description: Using only a single piece of cardboard, scissors and masking tape, construct an egg carton that will allow an egg to fall 20 feet without breaking. Idea: 1) Cut the poster board in to 2 halves. 2) Use one half to construct a cone. The cone should be large enough that the egg will fit into the open end of the cone but will go no farther than half way down the cone. (See figure 1.1.)
There are three different court markings. There are the Court Boundary Lines, which surround most of the playable court. The Center Line, which is the line under the net and divides the court into equal sides. And the Attack Lines, which are placed on both sides of the court and are one third the distance away from the Center line, and between that and the Boundary lines. There are five different zones and areas.

Solution for POW: Pool Party Part 1 (2 pt) The game of pool or pocket billiards is played on a table with 6 pockets (one in each corner and one half way down each long side. Our pool table will have pockets in only the 4 corners (A, H, L or S). In our problem, the ball must travel along the lines and bank off the sides until ending up in a pocket. Starting at each letter, count the number of jumps (line segments) it must travel until it goes into a pocket. In most cases (except for the corners) the ball can be hit in two directions, so determine both answers.
For this assignment we will be working on problem #68 from page #539 (Dugopolski, 2012). An 18-wheeler can carry a maximum of 330 TVs and no refrigerators, or no TVs and a maximum of 110 refrigerators. The diagram we were given shows the TVs on the y-axis and the refrigerators on the x-axis. In order to figure the
2. In the center the strips, about 3 cm from one end, place a dot of the marker to be tested. The dots should be about 0.2 cm in diameter and dark enough to be clearly visible. 3. Place about 2 cm of water in each glass.
“K = ½mv2 where K = kinetic energy” (Koehler, J., The Science of Pocket Billiards) When you strike another ball with the cue ball it is almost a perfect elastic collision. An elastic collision is one in which total kinetic energy as well as total momentums are conserved within the system. This can be shown by the two basic equations; Conservation of “Kinetic Energy: ½m1v1i2 + ½m2v2i2 = ½m1v1f2 + ½m2v2f2 Conservation of Momentum: m1v1i + m2v2i = m1v1f + m2v2f where m = mass of object v = velocity” (Koehler, J., The Science of Pocket Billiard) Since the cue ball has virtually the same mass as the other balls and the velocity of our second ball will always be zero, since we are striking a static ball with the cue ball. In addition this is considered a two- dimensional collision. From this we know that momentum is saved within the y component and within the x component.
They can be found inside as well as outside triangles. The circles located on the inside are called inscribed circles. Inscribed circles should touch each side of the triangle at a single point. The circles on the out sides are called circumscribed circles. A circumscribed circle touches each vertex of the triangle.
