Question $1[150$ Marks$]$ An aligned, short fibre composite has the following characteristics: $$ Fibre diameter $$ Fibre ultimate tensile strength $$ Interfacial shear strength $=17$ m $=3$ GPa $=60$ MPa a$)$ Plot the average fibre stress vs$.$ fibre length for this composite failing in tension. b$)$ If the length of the fibres $=0.$XY mm where XY are the last two digits of your student ID$,$ plot the normalized fibre stress vs$.$ aspect ratio, and explain the resultant plot in detail. c$)$ If the orientation of the fibres changed to $45,$ how would the critical length value of the fibre be affected?and lat two digits of my student ID is $10$
