The example at 5:02 I got the same final answer, but I did it differently. The distributed load on the 1.8 m bar, I saw it as as a trapezoid and used F = (1/2)(a + b)(s), then the center point going horizontal = [(2b + a)s]/[3(a + b)]. The load on that bar came out as 2.7 kN and 0.8 m away from point A.

@QuestionSolutions
2 жыл бұрын
This is how distributed loads are represented on diagrams. We don't write just 6kN. We represent it with respect to a distance. So you can think of it as "it starts with 6 kN/m at the top and goes all the way down to 0 kN/m." I hope that helps 👍 Please see your textbook for more info on this as it should be covered.

@QuestionSolutions

You only use positives and negatives during the process to find the resultant moment. That allows you to determine whether the resultant moment is clockwise or counterclockwise. At the end, you should indicate a direction with an arrow going clockwise or counterclockwise, not with a negative sign. Moments aren't negative or positive, they have a direction in 2D problems.

So 1.8m is not perpendicular, you can see that it's a slanted incline. What we need is the perpendicular distance, which would be 1.8cos60 plus the 0.6 m which is the halfway distance from where the 1.2kN force is applied. See 6:43, I show the distance.

That's actually done using geometry. I encourage you to draw out the shape to scale and use a protractor to see the angles, otherwise, you will need to identify how alternate interior angles and consecutive interior angles give us the 60 degrees. It's best done by extending the lines and seeing the parallel lines it creates. 👍

I am not sure of your question 😅 So if you look at 6:42, I show the perpendicular distance and how it's found with the light blue lines. Think of the total length as the bottom of a right angle triangle, then we can figure out that length using cosine, because it's adjacent over hypotenuse. So here, the hypotenuse is the 1.8 m, and the adjacent is the perpendicular length we want. So you get 1.8cos60, and then we still have the small distance at the very top, which is 0.6 m. Add those two values together and you get the total perpendicular distance. It might help to draw it on a piece of paper with a straight edge :)

In such scenarios where you have a hard time deciding if it's sin, or cos, I encourage you to draw that force alone on a piece of paper, neatly, and then looking to see which side corresponds with the angle. It might take an extra minute or two, but will help you in the long run :)
