With reference to figure 1, a plate, 75mm wide and 10mm thick, is joined with another plate as shown. The permissible tensile and shear stress in the welds are 50/mm² and 40N/mm². Determine the required length of each parallel fillet weld if length of transverse weld is 40mm.
(a) 11mm
(b) 9mm
(c) 8mm
(d) 7mm
This question requires clarification and I found it during a telephonic interview.
My doubt stems from the Butt Joints & Fillet Joins concept in chapter Welded and Riveted Joints of Machine Design
