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?

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 often do tectonic plates move? How often does climate change occur? What is the difference between spring tide and neap tide? How often does Japan have tsunamis? Spring tides occur when the moon is at it s full and new moon phases. Which of those two phases do greater spring tides ...
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,...
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...
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.
How does the asthenosphere move tectonic plates? Lithosphere and asthenosphere: The lithosphere (which consists of the Earth's crust and upper mantle) is situated on top of the asthenosphere. The lithosphere comprises tectonic plates. The asthenosphere is flowing and very viscous. ...
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 ...
This actually works really well because it moves the center of gravity to the center of the mower, adding further stability. Following that was the installation of the floor plates made of thick diamond plate. These were cut to size and screwed on with self-drilling screws so that both ...
