A load P is supported as shown by a steel pin that has been inserted in a short wooden member hanging from the ceiling. The ultimate strength of the wood used is 60 MPa in tension and 7.5 MPa in shear, while the ultimate strength of the steel is 145 MPa in shear. The diameter of the pin is d= 18 mm and the magnitude of the load is P= 20 KN. NOTE: This is a multi-part question. Once an...

1.47 A load P is supported as shown by a steel pin that has been inserted in a short wooden member hanging from the ceiling. The ultimate strength of the wood used is 60 MPa in tension and 7.5 MPa in shear, while the ultimate strength of the steel is 145 MPa in shear. Knowing that b = 40 mm, c = 55 mm, and d = 12 mm, determine the load P if an overall factor of safety of...

Problem 4 (3pts) The beam AB is supported by a single-shear pin connection at joint A and by a double-shear connection to member (1) at joint B. Member (1) is connected to the support at C with a double-shear pin connection. Member (1) has a cross-sectional area of 100 mm and a yield strength of 340 MPa. The pins at A, B, and C each have a diameter of 12 mm, and an ultimate shear strength of 270 MPa. Specifications...

An overhead crane runs on rails attached to structural columns by means of 25 mm thick mild steel brackets. The brackets are riveted to the column as shown using five 14 mm diameter rivets. The rivets have a shear strength of 100 MPa. Determine if the bracket can safety carry a downwards vertical load of P=20 kN. 1. If the bracket can safely carry the load, determine the factor of safety against eventual failure. 2. If you determine that the...

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)...

1. Fluctuating loading. The cold-drawn AISI 1040 steel bar (S590 MPa, S 490 MPa) shown in the figure is subjected to the following different cyclic loading conditions. Estimate the fatigue factor of safety based on achieving infinite life (use Modified Goodman method) and the yielding factor of safety. If infinite life is not predicted, estimate the number of cycles to failure. The fatigue strength modification factor f 0.87. For...
