(2) The figure below shows a bar that is made of AISI 4130 normalized steel and is loaded by the forces F=12kN,P=23kN.
(a) What is the safety factor of the design shown?
(b) If a transverse hole of 3 mm is to be drilled in the center of the 10 mm -diameter beam side. What is the change in the design factor?
(c) If a crack of length of 0.5 mm is noticed on the body of the 1 in -diameter beam. What is the failure stress values and the safety factor?
