When stacked wooden planks are bonded to act as a single beam, ______ must develop to prevent relative sliding between layers.
Bearing stress
Longitudinal shear stress
Direct tensile stress
Torsional shear stress
In beam shear analysis, it is generally easier to evaluate ______ shear stresses acting between layers than vertical shear on the cross-section.
Horizontal
Torsional
Thermal
Radial
For a rectangular beam section under transverse shear, the shear stress distribution with depth is best described as:
Constant throughout the depth
Linear with maximum at extreme fibres
Parabolic with maximum at neutral axis
Zero at neutral axis and maximum at top fibre
In bending of beams of rectangular cross-section, the maximum shear stress is larger than the average shear stress by:
50%
150%
250%
100%
The ratio (average shear stress)/(maximum shear stress) for a rectangular beam is:
1
2/3
3/2
2
A beam has a triangular cross-section (base = b, height = h). If shear force = F, the shear stress at the neutral axis is:
4F/3bh
3F/4bh
8F/3bh
3F/8bh
For a triangular section, maximum shear stress occurs:
At the neutral axis
At the top vertex (apex)
At half the depth of the triangle
At the bottom fibre only
In a rectangular section, shear stress varies parabolically with depth and is maximum at the neutral axis. Choose True or False.
True
False
In a triangular section, maximum shear stress occurs at the neutral axis. Choose True or False.
True
False
In a rectangular section, shear stress varies (a) with respect to y.
In a rectangular section, shear stress is maximum at the (a) axis.
In a rectangular section, tau_max = (a) × tau_avg.
For a triangular section, shear stress at NA = ( (a) ) F/(bh).
A rectangular beam section has b = 120 mm and h = 240 mm. At a section, the shear force V = 36 kN. Find the average shear stress tau_avg.
