Question #137243

. A 200 × 150 × 10 angle is to be welded to a steel plate by fillet welds as shown in Figure. If

the angle is subjected to a static load of 300kN, find the length of weld at the top & bottom.

The allowable shear stress may be taken as 75 N/mm2

.

Expert's answer

Given static loading =300 kN = 300 N ,here dimension is given as 200 ,

permissible shear stress= 75 ,here a+b=200

s= size of weld = thickness= 10 ,we know that

for single weld

on putting value we can get value of l

l= 303.09 mm

now distance of centroidal axis from bottom angle

b=55.3 and a= 144.7 so

and
