MEE 342 Dr. Masoud Yekani Fard HW 8, Due 04/29/2015 1. (75 points) Figure 1 shows a bar welded to a base with 3/16 in fillet welds on three sides using an E70 electrode. Material is A572 Grade 50 hot-rolled steel (Sy = 50 ksi, Sut = 65 ksi). What is the maximum static load P that can safely be applied?
Figure 1.
2. (75 points) Figure 2 shows a bracket welded to a wall with a fillet weld using an E70 electrode. Determine the fillet weld size needed between the tube and wall for a static load F = 2.5 kips. The material properties of pipe and wall are Sy = 60 ksi, Sut = 80 ksi. OD = 3.5 in, ID = 3.068in, b = 0.5 in, h = 4.2 in, a = 7in, l = 8.75 in.
