Question 3 128 Marks 2 rectangular beam shown in the figure is subjected to a fluctuating axial force. It fluctuates between 5 kN and 15 kN keeping its direction. The beam is to be machined to the dimensions shown in the figure with a transvers hole of diameter d-14 mm/ Material of the beam is AISI 1040 CD steel (S-590 stress concentration factor as 2.2. K Pa, Sy 490 MPa). Take...

Q3 A tensile apparatus is to be constructed which must withstand a maximum load 420kN. The design calls for two cylindrical support posts, each of which is to support half of the maximum load. The material, AISI 1045 Carbon Steel minimum yield and tensile strengths of this alloy are 310 MPa and 565 MPa, respectively. If the safety factor is 1.5, find: a) Working stress, ow (2 marks) b) Suitable diameter for these support posts. (2 marks)
