Hello, in this question we are given that there is a road it consists of bronze, aluminium and steel.
00:12
It is something like this.
00:15
This is bronze.
00:17
This is aluminium and this one is steel.
00:26
So area corresponding area is also given that is 700 ,000 and 800.
00:34
This is 700 meter square, millimetre square, thousand and eight hundred.
00:39
Sorry, this is 700.
00:43
This is 1 ,000mm square and this area is 800mm square.
00:50
And the forces are 20.
00:59
This is 10 in the right over direction, sorry.
01:04
And here it is 15.
01:06
And again here it is 15.
01:11
Okay.
01:12
So now we need to calculate the stresses in the different components.
01:16
So we will start from the right drawing the free body diagram of the structure.
01:20
So if this is the steel one, if you cut it from here, just rightward of this force 15 kilo newton.
01:32
So it would be 10 over here...
