Open questionCENAT2 marksNeeds review
The flange and web plates of the doubly symmetric built-up section are connected by continuous 10 mm thick fillet welds as shown in the figure (not drawn to the scale). The moment of inertia of the section about its principal axis X–X is
. The permissible shear stress in the fillet welds is 100 N/mm
. The design shear strength of the section is governed by the capacity of the fillet welds. 
The maximum shear force (in kN, round off to one decimal place) that can be carried by the section, is _____.

Open questionCENAT2 marksNeeds review
A simply supported prismatic concrete beam of rectangular cross-section, having a span of 8 m, is prestressed with an effective prestressing force of 600 kN. The eccentricity of the prestressing tendon is zero at supports and varies linearly to a value of
at the mid-span. In order to balance an external concentrated load of 12 kN applied at the mid-span, the required value of
(in mm, round off to the nearest integer) of the tendon, is _____.Log in to check the answer
