Hello students, firstly we determine the area of the weld.
00:06
The area of each filled weld can be calculated using the formula area equals to 0 .707 into leg length into thickness.
00:22
Since the leg length is not given so we assume that it is equal to the thickness of the steel bar which is 6 mm.
00:33
Therefore the area will be equals to 0 .707 into 6 into 6 which is equals to 25 .46 mm square.
00:49
If we calculate the total area, the total area for the two filled welds will be equals to 2 into 25 .46 which is equals to 50 .92 mm square.
01:05
Now we determine the shear force acting on the weld in the second part.
01:10
The shear force acting on the weld can be calculated using the formula shear force is equals to f into c minus b upon 2 whole upon h where f is the applied force, c is the distance from the support to the point, b is the width of the steel bar and h is the thickness.
01:37
Putting in the values we have 5 .267 into 152 minus 42 upon 2 whole upon 6 mm...
