All the pins are in double shear, and they each have a diameter of 14 mm. The average shear stress in each pin CANNOT exceed 70 MPa. What is the max magnitude of P that the beam can support

The joint proposed provides the connection (pivot) between the clevis 1 and the tie rod 2 by means of a shaft 3 stopped in translation by two elastic rings 4. the admissible resistance to shearing of shaft 3 is equal to 80 MPa. If the diameter d of the pin is equal to 50 mm, determine the maximum force F that can be transmitted by the connection

Each of the three rolled-steel beams shown (numbered 1, 2, and 3) is to carry a 64-kip load uniformly distributed over the beam. Each of these beams has a 12-ft span and is to be supported by the two 24-ft rolled-steel girders AC and BD. The allowable normal stress for the steel used is 22.5 ksi. Determine the section modulus for each girder and select the most economical W shape for the two girders using the table given below. (Round the final answer to one decimal place.)
