To analyze the type of loading and calculate the stress on the bolts, we need to consider the two different types of loading that the bolt can exercise, experience, tension and shear.
00:15
So, let's go through the each case.
00:18
So bolt in tension, when the plates are subjected to a tensile force which is pulling apart, the bolts experience tension.
00:27
Each bolts act like a bar under tension.
00:29
So to calculate the normal stress sigma on the bolts in tension, we will use this formula force divided by area, okay.
00:38
So applied force on the bolt is given to us 5000 newton and the area, so the diameter of the bolt given to us, i am writing down it here, so the diameter given to us 20 mm, okay.
00:59
So we can calculate the area from here by pi r square.
01:03
So it is, when we calculate it, this will be 3 .142 multiplied by 10 to the power minus 4 and meter square.
01:15
So by this we can get our sigma which is 1 .59 and multiply with the 10 to the power 7 pascal.
01:24
This is the normal stress on the bolt in tension.
01:28
Now bolts in shear and bearing, shear and bearing.
01:38
So when the plates experience a force that tends to slide them past each other, the bolts experience shear...
