For each question some of the dimensions or forces are given as values that vary with " ( x, y ) and ( z^{prime prime} ). Firstly, these values should be calculated and noted at the beginning of the problem solution. The " ( x, y, z^{prime prime} ) letters are the last three digits of your Student ID. Ex: If the Student ID is 020200123 , then ( x=1, y=2, z=3 ) and ( P=10+x+2 y+5 z=10+1+2 imes 2+5 imes 3=30 mathrm{kN} ) NOTE: The answer sheet you will upload to Ninova must be a white A4 plain paper. You should write your Student ID and Name&Surname on the top left corner and the Page Number on the top right corner of each pages. Q1: Draw the internal force diagrams ( (N, V, M) ) for the given beam and loading condition. [ P=10+x+2 y+5 z[k N] ] 02: For the system given in the figure, if the load is acting at point B; a) Check the safety of the bars ( B C ) and ( A B ). Note that the cross sections of the bars are identical. b) Calculate change in lengths of ( B C ) and ( A B ) bars ( left(Delta L_{B C}= ight. ) ?, ( Delta L_{A B}= ) ? ( ) ) and determine the displacement of point ( B ). c) Based on the connection detail at point ( C ) (Detail ( C ) and section 1-1), determine appropriate pin diameter to transfer the shear force safely. For the bars: [ sigma_{ ext {all }}=14 mathrm{kN} / mathrm{cm}^{2} quad E=21000 mathrm{kN} / mathrm{cm}^{2} ] [ P=10+x+2 y+5 z[k N] ] For the pin: [ au_{mathrm{al}}=14 mathrm{kN} / mathrm{cm}^{2} ]
