Hello students, according to the question we are going to find out the steel stress.
00:08
For that first we are going to use the equilibrium equation for force.
00:15
Summation of f is equals to 0.
00:19
So what are the force acting on that object will be rd minus p1 minus p2 plus ra is equals to 0.
00:32
If you resolve this equation we will get the equation as ra plus rd is equals to p1 plus p2.
00:51
This is the equation from force equilibrium formula.
00:56
Now we are going to use sigma ab plus sigma dc plus sigma cd equation.
01:13
As per this we are going to draw a diagram here.
01:18
This represents the free body diagram especially for the stress in steel.
01:24
P1 minus rd and here also p1 minus rd.
01:34
This is only for steel free body diagram for the steel.
01:39
Now we are going to find out the rd value.
01:49
For that we are going to write down the equation ra minus 350 by abeb plus p1 minus rd divided by as es plus into 250 minus rd into 100 divided by aal plus eal.
02:44
Because we have three different materials there but we need especially stress for steel alone.
02:56
Now we are going to apply all the values in the formula so that we will get the resolved value is equals to 0 here...
