The given data is the allowance bending strength sigma all is equals to 160 mpa and the free body diagram of the beam is this is the free body diagram of the beam.
00:23
So, there is ay and there is ax and there is by and there is bw0 this is the diagram and there is 30 meter 3 meter and 3 meter.
00:56
So, the reaction force giving 2 symmetricity of loading.
01:02
So, ay is equals to 1 upon 2 w0 multiplying by 3 meter.
01:10
So, ay is equals to minus 1 .5 is equals to 1 .5 w0 and the maximum bending moment at mid span of the beam.
01:29
So, the maximum bending moment at mid point mid stem mid span of the beam is mmax is equals to mmax is equals to 1 .5 w0 multiplying by 3m minus 1 upon 2 w0 multiplying by 3m multiplying by 3 upon 3m.
02:26
So, mmax is equals to 3 w0 and m newton meter.
02:37
So, the cross section of the beam is so the cross section of the beam this is the cross section of the beam...
