Question

The simply supported beam carries a uniform load. of 30 kN/m is shown in Figure 3. Due to a certain requirement, maximum deflection should not be more than 1/360 of the span length. If the allowable bending stress, Ơalkw-168 MPa and allowable shear stress. llo 110 MPa, choose the lightest wide flange beam from Appendix. Given data E-225 GPa, p 7850 kg/m3. Assume A is a pin and B a roller support Rasuk yang dsokong mudah Disebabkan sebuah keperluan tertentu, pesongan maksiman harus tidak melebihi 1/360 panjang rentang Jika tegasan lentur yang dibenarkan, uto 180MPa dan tegasan ricih yang ibenarkan, tall 120 Mpa pith berat rasuk bebibir lebar yang teringan p-7850 kg/m. Andaikan A adalah pin dan B sokongan roda) beban seragam. 30 kN/m dihnjukkan dalam Gambarajah 3 di dalam appendix. Diberikan data E -225 GPa r (20 Marks /Markah) 40 kN 40 kN 30 kN/m 1.2 m 2.4 m 1壬 26 012 Wide-Flange Sections or W Shapes SI Units 03 78 22 19 64443 64 42 87-10 36 31 25 571 753 Flange 87 x-x axis 19 84 Ares Depth hickness width thickness 22, 1, his 0.2 45 34 200 65 45 84嚣抑120 104 87 by- mm-ION 005 004 les 102 101 101加250 004期惯02 101 zia 200 200 200 013 65 102 194 53 52 102 102 100 d| mm | Sus $10崩$10 ,, RA,,拗200 250 201 220 m zio 210 200 201 200 102 197 52 160 53 150 al 500 AND $30 | 000 200 1 1 2 2 2 000 100 75 170 2 432 000 2 130 ign-120 67 " 33 24 21 140 67 45 22 18. 100 86 46 36 22 37 30 22 14 2 19 0 7 5 3 2197542 432321 × 0000000 200 200 200 200 200 150 150 150
