1. A steel plate has been welded to a steel structure using fillet welds. It needs to support a weight with very little chance of yielding. What maximum weight, F, can the welds support, with a safety factor of 4.0 on yield? Remember that you need to treat the weld as a "beam." E60 weld rod used: Su = 60 ksi Sy = 48 ksi 3 in.

Question 1 (30 Marks) Plate A is fillet-welded to Plate B as shown in Figure 1. Plate A and Plate B have the same material properties Both plates are 10 mm thick. There are two holes (with a diameter of d) in Plate A. It is assumed that weld failure will not occur (a) If Plate A has a yield stress (fy) of 350 MPa and an ultimate tensile strength (fu) of 450 MPa, what is the maximum load (P)...

Question 1: A rotating shaft with a diameter of 30 mm is made of 1018 cold-rolled steel. The stress concentration factor is 2.366, and the shear stress concentration factor is 1.75 respectively. The notch sensitivity is 0.78 and for shear it's 0.96 Estimate the factor of safety guarding against fatigue failure using modified-Goodman and Soder- berg for each of the following loading conditions: a) The shaft is subjected to a completely reversed torque of 120 N.m in phase with a...
A rotating shaft is made of AISI 1035 CD steel is subjected to an axial load of 710N
A rotating shaft is made of AISI 1035 CD steel is subjected to an axial load of 710N, a fluctuating torque load from 60 to 120 N.m, and a completely reversed bending moment of 160N.m. The shaft has a diameter of 30mm, and operates at T=250°C, and has a life reliability of 95%. Note that the fatigue stress-concentration factor for bending Kfb is 1.49 and that for torque Kft is 2.65..1. Draw the Yield (Langer) line 2. Modified Goodman line. 3. Calculate...

HOMEWORK 1: At the Cullowhee Zoo one of the most popular attractions is watching the hippos dive off of a specially constructed diving board into the Tuckaseegee River. They are magnificent, you should really go some time. The diving board consists of a very strong wall with a support pipe embedded into it with very strong concrete. The pipe is welded together with a diving board that has a hollow, rectangular cross section. BOTH THE PIPE...
