a); Cross section of a beam is an isosceles triangle having base width 400mm and height 600mm. It is placed with its base horizontal and subjected to a shear force of 90KN. Find the intensity of shear stress at the neutral axis. Ans: TNA = IMPA. A rolled steel joist simply supported over a span of 4m and carrying a udl of 80KN/m has the following dimensions: Overall depth 350mm, each flange 150mmx25mm, web | 300mmx12mm. Determine the magnitude of bending and shear stresses at the junction of web and flange at a section Im away from the support. A rod of circular section is subjected to a shear force F on a plane perpendicular to its axis. Find the maximum shearing stress in terms of the shearing force and the rod diameter. central concentrated load, find the ratio of the maximum bending stress to maximum shear stress in terms of the span and rod diameter. b) c) (b) If the rod is used as a beam simply supported at its ends and having a
