Beer, Johnston & Dewolf, 2004
1f the outward normal of the face of a section is in th& positive direction of the x-
axis, then the positive shear force vector is in the positive _v-direction and the
positive bending moment vector is also in the positive r-direction ; if the outward ...

2.23a and the discussion in Art. 3.2 that positive bending moment induces tensile
stress in the bottom fibers of a beam and compressive stress in the top fibers. A
study of Fig. 2.23b will show that this condition is reversed in the case of negative
...
Stanley W. Crawley, Robert M. Dillon, 1993
In the case of a beam, a positive shear force acts clockwise against the material (
Figs. 4-8b and c) and a negative shear force acts counterclockwise against the
material. Also, a positive bending moment compresses the upper part of the
beam ...

Strength Of Materials: A Practical Approach
Such a moment induces downward deflection in the beam as shown in
discontinuous lines in the figure, and is known as positive bending moment.
Since the moment causes the beam to sag (deflect downwards, like a suspended
rope), it is ...
Positive bending moment diagram is sometimes drawn on tension face of the
member, otherwise +ve or -ve sign is to be marked in the diagram. Fig. 5.3

Applied Engineering Mechanics: Statics and Dynamics
Positive shear is where the resultant force acting on the portion of the beam to the
right of the section considered acts downward, while a positive bending moment
causes the beam to bend such that its top surface is concave. 9.4 Shear-Force ...
