P P 50 KN $ $2 Si Si Sto Sur 4 m 4 m Dimensions and loading of a truss beam are given in the figure. a) Calculate all the member forces of truss by using method of joints and list them in a table b) Calculate the member forces of S2, Ss and So by using RITTER method of sections. c) Check the safety of the members Ss and Sus by using allowable stress 0.5 Load P is given as a value that varies with a band The "a, b, c letters denotes the last three digits of your Student ID number. P = 100 + a + 2b +3c [kN] Ex: If the Student ID is 020210123, then; a=1, b=2, c-3 and P = 100+1+(2x2)+(3x3)= 114 KN if c = 1, 3, 5, 7 or 9, then; Cross-sectional area of truss member Se Is A=100cm Cross-sectional area of truss member Su is Au=200cm O = 1 kN/cm (timber sections) if c = 0, 2, 4, 6 or 8, then; Cross-sectional area of truss member Se is As=7cm? Cross-sectional area of truss member Sus is Au=17cm? 0. = 14.4 kN/cm(steel sections)
