Question 1 [33] Vraag 1 [33] A solid CAST cantilevered bracket comprising of al solid square section and a solid rectangular section, as shown below, is used to support an axial load F through a 40 mm diameter hole. The bracket is welded onto a support member, as shown. 'n Soliede GEGOTE kantelbalk met 'n soliede vierkantige gedeelte en 'n soliede reghoekige gedeelte, soos hieronder getoon, word gebruik om 'n aksiale las F te ondersteun deur 'n gat van 40 mm. Die kantelbalk word aan 'n ondersteuning vasgesweis, soos aangedui (a) Using a suitable failure criterion, determine the maximum force that the cantilever can support, using a design factor of 3. Assume no cracks in the cantliver. [7] (a) Gebruik 'n geskikte falingskriterium, en bepaal die maksimum krag wat die kantelbalk kan dra. Gebruik 'n ontwerpsfaktor van 3. Neem aan dat daar geen krake in die kantelbalk is nie. [7] (b) Based on the load in part (a): (i) (b) Op grond van die las in deel (a): Determine the size of the fillet weld to ensure safe operation. [13] (i) Bepaal die grootte van die vulstraalsweis om veilige gebruik te verseker. [13] (ii) Specify a suitable weld electrode based on the AWS standard, and verify that the length of the weld is adequate for the load. [5] (ii) Spesifiseer 'n geskikte sweiselektrode gebaseer op die AWS-standaard, en verifieer of die sweislengte voldoende is vir elas. [5] (c) Determine the critical depth of a surface crack on the cantilever, as shown in the diagram. (c) Bepaal die kritieke diepte van 'n oppervlakskeur Assume a fracture toughness of 10 MPa√m. [8] op die kantelbank, soos in die diagram getoon. Aanvaar 'n breuksterkte van 10 MPa√m. [8] 200 300 100 120 AISI 1040 Mode 1 crack through section Modus 1 kraak deur snit h On 3 sides R4 08 140 All dimensions in mm. Alle afmetings in mm. 240
