◦Describe what this graph looks like. Include information about the intercepts, the type of line needed, direction of the line, and region(s) shaded to fulfill the inequality. Any details which are pertinent to know about the graph should be mentioned. ◦Evaluate the findings in this graph. Pick a point in the shaded area and give its coordinates, and then discuss what those numbers mean in terms of rockers and board feet of lumber.
D. Thesis Statement: After this demonstration you will have the confidence to try snowboarding at least once! E. Establish Credibility: I have been snowboarding for the last six years and have gone to several mountains around the western coast. F. Preview Main Points: There are three things I am going to talk about today, Gear, how to fall correctly and three basic snowboarding maneuvers. Transition Sentence: One of the most important aspects of snowboarding is your gear; after all you want to have fun when you go! II.
5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
Requiring either a long cruiser or a shorter hybrid type board. A kicktail is useful on a commuter board as well, allowing the rider to pick up the front of the board to drop off curbs or efficiently navigate sidewalk turns. The wheels will, usually, be a medium to large size, allowing for rolling over small surface obstacles. Cruising and carving are where the surfing feel really comes in to play. The wood used to make boards for this style will generally be more flexible than say for downhill riding.
The further an object is from its axis of rotation, the further its linear speed. If the center of your back is the axis of rotation, the further your hold your stick out and whip it forward will cause the release of the ball to travel faster. The arms with the stick in hand act as a series of levers which propels the ball forward. Your feet causing friction with the ground allows you to twist your body and transfer the energy from linear momentum to rotational momentum. This allows your body to coil and transfer more kinetic energy into the shot.
The twirling slows down the seed and allows it to catch a crosswind that will carry it farther away in order to disperse it. It is similar to a propeller because of the wing of the seed has the shape of one blade of the propeller fan. I could help students to understand how a propeller works or why the maple seed twirls when it falls by explaining the idea of air resistance and surface area. The maple seed falls slowly down to the ground because of the low air pressure that is created just above the thicker edge of the wing of the maple seed. This low air pressure results from the motion of the wing as it travels down in a spiral.
Warm air can also rise to form clouds, and blizzard snows, as it drifts up a mountainside. Blizzards can cause power outages and make temperatures inside of homes drop dangerously low. Strong winds combined with a temperature just below freezing create a miserable chill factor. A chill factor is what the human body ‘’feels’’ rather than what the actual temperature is. This dangerous condition can result in frostbite or hypothermia, which can be deadly.
It was a wheel that was under the track and would keep the train coasters from going off track. This was a big step in Roller coaster designing and in Coaster History. Now designers can make steep drops and sharp turns and still have the coaster cars be going at exhilarating speeds. Miller’s “Miller under friction wheel” is still used in almost all roller coasters. He also had his share in making “scream machines”.
These weights hang off the sides of the wheels and pull on the string at different angles, the objective is to find the point at which all the weights pull on each other so the center of the string is in the center of the force table. This was found in the lab by slowly adding weights till the right mixture was found. The forces are recorded and then shown through vectors. Adding the Vectors up shows that you have a system of equilibrium or not, depending if there is a gap between the first and last vector. The results came out to be complete vectors with the corresponding degrees of the angles with we experimented on.
