As we explored on the last two pages, flaps and slats enable a pilot to move an aircraft through three-dimensional space. In other words, the pilot alters the plane's orientation around its own center of gravity, producing torque. Imagine this center of gravity as a fixed point in the mi...

How do subduction zone earthquakes cause tsunamis? What causes Earth's lithospheric plates to move? What drives the process of plate tectonics? How can gravity's role in tectonic plate motion be described? Explore our homework questions and answers library ...
Is normal force the y-component of the force of gravity? Why does the normal force decrease as the angle increases? A person applies 100N of force on a shelf and it doesn't move, why is the shelf not moving? What could be done for it to move?
Like boats, they are made to move to avoid overstressing and stresses on the structure. To minimise these movements, the platform is usually fitted with heave plates, which are surfaces below the waterline. Semi-sumergible. This design seeks to minimise the surface area exposed to the water,...
At 18, Katie Stubblefield lost her face. At 21, she became the youngest person in the U.S. to undergo the still experimental surgery. Follow her incredible story.
Another upgrade I figured out after actually taking her sailing would be to rig up a bungee/shock cord system that will hold the daggerboard both in an up and down position. With the current setup, the centerboard is held down by gravity and must be pulled out of the slot when beaching...
Gravity flow or a pump is used to move the liquid from the lower concentration chamber through the higher concentration chamber into the gel casting plates. Be sure to wait until you are ready to begin pouring before you add the ammonium persulfate (APS) and TEMED (the ingredients that ...
Gravityis the force that pulls objects toward the center of the Earth. In the case of yourDIY marble run, gravitycauses the marble to roll down the ramp. The steeper the ramp’s angle, the more gravity pulls the marble downward, making it move faster. You can demonstrate this by comparin...
All hulls have a Center of Buoyancy (CoB) and a Center of Gravity (CG). The CoB is mainly related to the hull shape, whereas the CG is related to where the weight is placed in the hull. The higher the CG is above the COB, the less stable the hull. No matter how you move the...
