This is a video example showing how to calculate the cent of gravity and the center of mass for a simple collection of objects in a uniform gravitational field. That is to say, "g" is the same for every object.

Great video. Clear narration and explanation. No extraneous filler, just giving me the information I came for. Keep it up!

Thank-you Sir, this helped a lot! ;)

Ok, understood. Now, where would the center of mass of the system be applied IF there would be now an additional weight on the same vertical line as the center of mass found?

I've been given a question that is almost exactly like this one only difference is that there diagram only shows the distance from the left edge of the beam (Point A/where to calculate from) to one side of the object then the length of the object and then from the end of the object to the end of the rest of the beam and not the center of the object. Is this only meant to calculate from the left edge of the beam to the center of each object? The way the question was given to me was unfortunately confusing to me.

Say I take the diagram and state, there is a nail balancing the beam. The nail is in the center of the beam and the beam balances perfectly. Were to put the two buckets to keep the beam steady. How would you set up the equation? X_cm = (mx1+mx2+mx3)/(m1+m2+m3) = 0?

Work out the centre of gravity for each of the two components. Using the distances from 'A' to the centre of the beam then multiply by the weight of the beam. Then from 'A' to the centre of the spacing collar then multiply by the weight of the collar. Now add them together (w1 x d1) + (w2 x d2) =? Once you have added these together, divide by the overall weight of the beam and spacing collar.

How did we find the giometrical thingy for the beam?? Is the formula or did we just guess

Any videos about chemistry? As how you calculate the pH-worth of a substance. :)

centroid is the geometric center of the body or line (mass less body ) , than how you find Geometric center of Beam because it beam have mass 15kg . ????

how did you get 4m instead of 5 when its 5m from the 1m on the leftside?

@dirkvanzuijlen1962 3 жыл бұрын

what if a mass is totally on the left side of th beam at x=0

Where did you get the 1m,3m, and 4m?

@@drahcirombina73 I know this is two years way too late, but the distances "1m, 3m, and 4m" are in correlation to the beginning/far left-side of the board. In this example, the first weight is 1m from the edge, the center of the board is 3m, and the final weight is 4m from the left-most edge. Hope that makes it easier, if you were still wondering, lol.

everyone saying perfect video, this shit was not clear. How tf did he get 3.0 and 4 meters

@Smalls1 2 жыл бұрын

in the problem it shows the 4 meter distance from the left edge for the 15kg weight. The 5kg is the weight of the 'uniform' beam (uniform being the key word), so we can infer that the centre of the mass would be in the middle which is half of 6 meters = (3m).

@alexz4006 2 жыл бұрын

4 meters is given, the distance from the left edge of the beam to the 15 kg object thats why those multiply together in the numerator. This applies for the other objects so you multiply the mass times their distance from the left of the edge in this example. The 3 meters is because the 5 kg beam is uniform and its center is at 3 m since the beam is 6 m long . So you multiply 5kg(3 m) because of the same thing i explained earlier. Everything was well explained you have to work on your analysis
