So, it is given that ina is equal to 981 .3 in to the power 4 and wo is given as 300 of lb divided by feet and p value is given as 2 of lb and the sigma of max is given as 1400 psi.
00:24
So basically, here we have this is r1 and this is r2 and let us say it that anv.
00:36
Let us name that this is a and this is b and this is c.
00:41
From here it is c.
00:43
So, here it is plb with this w here and from here to here it is 9 and from here to here it is 12 inch.
00:53
So, from side bending moment diagram, we can see that the maximum moment occurs under the point of load that is summation of ma will be equal to 0.
01:04
So, r2 which is multiplied by 12 will be equal to p which is multiplied by a plus w which is multiplied by 12 square divided by 2.
01:16
So, this will be 12 of r2 which will be equal to 9p plus 300 which is multiplied by 12 square divided by 2.
01:24
Here we have r2 will be equal to 1800 plus 0 .75 of p...
