Let her performance inspire you.Concealed Handgun Permits can now be displayed on the LA Wallet Digital Driver's License App Lara Jacobs at the TED圎dmonton conference shows how far one can go in constructing a chain of center of mass balance points. You can even tape the toothpick to the side of your glass. We used a salt shaker to hold the vertical toothpick, but any support will do. Use round toothpicks rather than flat ones it's hard to get the flat toothpicks lined up correctly. Now the forks are balanced right at the burnt end of the tooth pick (figure 6).įor an even more impressive display, you can balance the forks on top of another upright toothpick as in figure 7. Let the toothpick cool and knock off any remaining ash. The flame should go out just as it reaches the rim. To do it, light the end of the toothpick inside the glass and let it burn all the way to the rim. This piece weighs so little that removing it will hardly affect the center of mass, and the forks should remain balanced. The effect can be made more dramatic by removing the portion of the toothpick inside the glass. It's hard to appreciate by eye that the handles of the forks are balancing in the other direction. Although the center of mass really is supported by the rim of the glass, it looks like the forks are balanced way out beyond the edge of the glass. ![]() This makes for an improbable looking balance. Figure 3 shows the forks balanced on a fingertip with the aid of the toothpick.Īlternatively, we can rest the center of mass on the rim of a glass (figure 4). We can fix the situation by adding a toothpick that reaches back to the center of mass. There's nothing there for the support to hold up. Since there is nothing at that location, it would be hard to balance the forks right at that point. The center of mass of the forks is located in between the two forks, at the red dot in figure 3. Take two forks and wedge the tines together as in figure 3. The center of mass of an object doesn't necessarily have to be inside the object. You can now balance the state of Massachusetts on a pencil by putting the point directly underneath Worcester. ![]() In contrast, the Boston is the center of the universe, but only according to Bostonians. This location is the center of Mass., just south of Worcester. No matter how you hang the state, the vertical line down from the hook will always pass through the blue dot. The center of mass must be at the intersection of the red and blue lines (blue dot in figure 2). Once again, half the weight of the state lies to the left of the red line and half to the right. Now hang the state from Boston (red dot in figure 2). (Otherwise, the state would tilt to a new position.) The center of mass must therefore be somewhere along this line. Half the weight of Massachusetts lies to the left of the vertical dashed blue line and half lies to the right of the line. Take an irregularly-shaped object, like Massachusetts say, and hang it from the northeast corner of the state (figure 1). Finding the center of mass of an irregularly shaped object is a little harder, but there is a surefire technique that will lead you to it. COM of irregular objectsįinding the center of mass of a symmetric object like a book is fairly easy it's midway between the edges as you'd expect. Support the object directly under the center of mass and it will balance, no matter which direction you orient the object. The center of mass of an object is a balance point. This center is known as the "center of mass" (COM), or sometimes "center of gravity" (COG). When you get it to balance, you'll notice that the eraser is just below the center of the book. Take a book and try to balance it on the eraser end of a pencil. ![]()
