* Solution in last pggg uestions —12 rueiFalse El when the shearforee along a section in zero , bending moment is maximum
or minimum. Bl thetransverse shear stress acting in a beam of rectangular cross-section,
su bjeoted to a transverse shear load is uniform. 1D] the bending shear stress induced in a beam is uniform through out the
cross seoti on. lll ifthe bending moment along the length of a beam is constant , then the
beam cross section will not experience anv shear stress. 12l In a simplv supported beam carrying a connected load at mid—spam, both
the shear force and bending moment diagrams are trianglular in nature
without anv oh ange in sign. Solution of Question 7 : ...
