Question

If allowable shear stress in weld is 90 n/mm2 the strength of a standard 5mm size fillet weld per m length would be

Answer 1

We will apply the formulae below :

Tensile strength = Allowable stress × throat length

Convert mm to m we have :

5 / 1000 = 0.005m

Convert the allowable stress to N / m²

1000000 mm² = 1 m²

90 / 1000000 = 0.00009 N / m²

Substituting in the formula :

0.00009 × 0.005 = 0.00000045

Answer 2

Answer:

Explanation:

We will apply the formulae below :

Tensile strength = Allowable stress × throat length

Convert mm to m we have :

5 / 1000 = 0.005m

Convert the allowable stress to N / m²

1000000 mm² = 1 m²

90 / 1000000 = 0.00009 N / m²

Substituting in the formula :

0.00009 × 0.005 = 0.00000045

4.5 × 10⁻⁷
