Home » Machine Design » Machine Design Miscellaneous » Question

A 60 mm long and 6 mm thick fillet weld carries a steady load of 15 kN along the weld. The shear strength of the weld material is equal to 200 MPa. The factor of safety is

1. 2.4
2. 3.4
3. 4.8
4. 6.8

Correct Option: B

P = .707 t × L_e × τ_s.

	15 × 10³	= τ_s
	.707 × 6 × 60

∴ τ_s = 58.94 MPa
Given shear strength of material = 200 MPa

FOS =	200	= 3.4
	58.94
