Bending Moment

In general, we can define the bending moment as the reaction induced when a certain amount of load or force is applied to an element which makes it bend.

Question

5.) A pin made of steel is inserted in a short hanging wooden member and is used to support load F = 20
kN as shown in the figure. The ultimate strength of the wood used is 60 MPa in tension and 75 MPa in
shear. On the other hand, the ultimate strength of the steel is 150 MPa in shear. If the pin diameter is 16
mm, determine (a) the factor of safety for the pin; and (b) the required values of b and c if the factor of
safety for the wooden member is to be the same as that found in part (a) for the pin.

The cross section of a steel tube under a loading condition is shown below. The tube is attached rigidly to a wall at an end while being subjected to load P at the opposite end at the location shown in the second figure. It is made of a steel with the yield strength (Sy) of 180 MPa and has a length of 0.5 m. Using maximum shear stress theory, determine the maximum load P that can be applied before yielding occurs. Use 2 as the factor of safety.
In the structure shown below (Figure 3), two forces of equal magnitude (P) are applied along the horizonal and vertical directions at point C. The beams are connected by pins at A, B and D. The pins A, B and D have diameters of 8 mm, 12 mm, and 14 mm, respectively. The failure stress for all the pins is Tfail=120 MPa and the failure stress for the bars between B-D is o fail =300 MPa.

A steel plate 5/16 in. thick is embedded in a horizontal concrete slab and is used to anchor a high-strength vertical cable as shown in the figure below. The diameter of the hole in the plate is 0.75-inches, the ultimate strength of the steel used is 36 ksi, and the ultimate bonding stress between the steel plate and concrete is 300 psi. The designers considered a factor of safety of 3.60 is desired when P = 2.5 kips. Address the following: (a) Identify three potential failure modes for the complete system. For each mode develop a sketch which idealizes the mode of failure. (b) If you where required choose dimensions for the plate ("a" and "b"), how would you size these dimensions? (c) For one of the failure modes identified above, perform an analysis to determine adequate plate dimensions ("a" and "b") to support the required load of 2.5 kips with the established factor of safety. in.
