127.  A diagram which shows the variations of the axial load for all sections of the span of a beam, is called

128.  The width b and lepth d of a beam cut from a wooden cylindrical log of 100 cm diameter for maximum strength are:

129. Beams of uniform strength are preferred to those of uniform section because these are economical for

130.  A 8 metre long simply supported rectangular beam which carries a distributed load 45 kg/m. experiences a maximum fibre stress 160 kg/cm2. If the moment of inertia of the beam is 640 cm4, the overall depth of the beam is

131.  If a rectangular beam measuring 10 x 18 x 40Q cm carries a unformly distributed load such that the bending stress developed is 100 kg/cm2. The intensity of the load per metre length, is

132.  In the cantilever truss' (Fig. 6.1), the horizontal component of the reaction at A, is

133.  The direction of the reaction at support B of a truss shown in Fig. 6.3 will beFig. 6.3
