Determine the reactions at the supports.
13 Business students watched this video and disliked it because they didn't know how the get the area of the triangle
This is funny because after watching this video I tried one on my own and got the wrong answer because i forgot to divide the area of a triangle by 2. I didn't know why I got it wrong until I read your comment lol.
😂😂😂
;) That's funny!
thanks for doing these and keeping them up. I appreciate it. I keep watching them to pass my exams.
Excellent!! Taking this class for the 2nd time. First time watching these videos and my grade has gone up.
Same pare
you're saving many lives
I'd like to talk to you about engineering and mechanics.
This guy is the reason I passed this course
could you please do excersise 5.19? thanks!!
thank you thank you thank you thank you thank you...
thank you from my heart
Gift from heaven!!! Thank you so much.
how did get your F2 distance of 5 when the total distance on the left side is 3?
The F2 action in the centroid of triangle which is 2/3 * 3 +3 = 5
hello nice video.. but how do we solve this if we arent given any parameters to work with
how does u determine the place of F1& F2
Why do we take F2 from 1/3 of the distance from the base?
because the centroid of a triangle is at 1/3. look it up on images to visualize it.
Suppose B is place at a meter from where it is, how would you go about it?
Hello can someone tell me why 5 was used here?
Thank you. Didn't realize it was so simple
Anyone know why he used 1/3 for F2? That's the only part I was unsure of from the example.
It's a rule..
Moment calculations use center of mass in the x direction for distributed forces. In a triangle, the center of mass in the x direction is 1/3 the distance of base, away from the corner where the right angle is.
Its because of the centroid of a TRIANGLE. The centroid of triangle is located by two points, 1/3 of the triangle from left OR 2/3 from left.
Thank you brother from my heart..
Can you do question 5-12?
Thank you so much!
please do 5-14
So....WOW...light bulb moment when you erased the triangle! Very Good step!
I'd like to talk to you about engineering and mechanics.
i added to find by and the answer was wrong i dont know what he did to find by can anyone help
can someone help me? I'm confused, I substituted the f1, f2 and Ay, but the answer that I got is different from the answer given. pls help me understand
Hello, am I too late? He converted it to kN before adding and subtracting them.
you made soo easy thanks man
why is force equal to area can u please explain the technicality?
អរគុណលោកគ្រូ
Should it be 1.825kn, or really 1.875kn? I got 1.825
why is that distance 5 instead of 6 for F2's moment
It's the distance from the arrow of F2. So for triangles you multiply the base times 2/3. In that case 3(2/3) giving you 2. So you take 2m + the other 3m (from F1 to B) which equal 5m.
Thanks...
determine the reaction at the supports, then draw the moment diagram. The moment of inertia for each segement is shown in the figure. Assume A and C are rollers and B is a pin. Take E = 200 GPa
why was F2 placed where it was it was not explained.
I would like to know as well
its a rule of distributive forces... triangle's are always replaced with a force 1/3 away from the longest length, where rectangles are replaced with a force directly half of the length. look at his videos of load distribution, they explain it
coming in clutch
The sum of the upward forces is not equal to the sum of the downward forces why?

I got 1825, not 1875?
Legend
Why 1/3?
Because the center of a right triangle is always 1/3 from the side perpendicular to x-axis.
@David Valle He does this because the force has to be measured at the center of mass of the triangle. The center of mass I believe is called a centroid. This goes for the rectangle as well, which is why the force is put in the center of the rectangle. When the taller side of the triangle is on the left, the center of mass is at 1/3 the length of the triangle. If the taller side of the triangle was on the right, the center of mass would be at 2/3 the length of the triangle. Sorry, that was a lot of explanation, but hopefully that helps.
How he get 300kn
what stresses me out is that this doesnt look anything like the answer my teacher gives me
Helllo,
Why is F2 distance 5 not 6?
because F2 5m is the distance from point B
larry robinson
2/3(3) + 3 = 5
Where did you get 2/3 from? I don't see it. Thanks
F2 is placed 1/3 away from point A, so the remainder of the triangle is 2/3.. which is equal to 2m. then add it to the length of the rectangle to get a total of 5m
cass ass thank you for that explanation. Currently getting whipped in statics. But my own fault, just not spending enough time on it.
howwww putek di ko makuha yung last

😮 AAA anything
Sir can you please intergrate for me acrtan^ 2
