Hello students, in this question given as this diagram and now we have to calculate the all support reactions such that at point a and at point b, ra and rb.
00:12
So, for the vertical force balance we can write ra and rb acting in the upward direction, this is equal to 20 kn in downward direction plus 10 kn per meter.
00:33
So, this is a spring load per meter, so 10 into spring is of 2 meter, 2 plus the rod balance will be equal to the 1 by 2, half of 60 kn per meter into 6, length is 6 meter and plus 30 kn.
01:02
So, after calculation we will get ra plus rb is equal to 250 kn, equation number 1.
01:14
Now, we have to calculate the moment about the point b, such as moment about the point b is equal to 0, so this will be 30 into 2 kn into here, 1 by 2 into 60 into 6, this force, this load will act at the distance 1 by 3 into base and here base is given as 6 meter, so this is 6 meter is equal to 2 meter from the highest point...
