In the given question, we have not mentioned what is sigma all and t all.
00:12
So, sigma all will be 12 mpa and t all will be 25 kpa that is 0 .85 mpa.
00:39
Finding reaction ma will be equal to 0 that is 2 4 times 1 plus 4 .8 times 2 minus rb times 3 plus 7 .2 times 3 .5 will be equal to 0.
01:20
From here, 3 times rb will be equal to 37.
01:29
Rb will be equal to 12 .4 kw.
01:40
So, ra plus rb will be equal to 2 .4 plus 4 .8 plus 7 .2.
01:56
From here, ra will be equal to 2 kw.
02:09
From sfd that is given as it is 2 .4, it is 4 .8 and this force is 7 .2 and this force is 12 .4.
02:41
The sfd will be this and the points will be a, c and b.
03:00
The values are 0 .4, 5 .2 and 7 .2.
03:05
It can be seen that at point c, mc is maximum.
03:16
Therefore, mc will be equal to 7 .2 times 0 .5 that will be 33 .6 knsigma is equal to my divided by moment of inertia.
03:42
Sigma given is 12 is equal to 3 .6 times 10 to the power 3 times 10 to the power 3 times 150 divided by 2 divided by b times 150 to the power 3 divided by 12.
04:07
From here, b will be 80 mm as t is equal to my divided by b multiplied by i...
