| Summary: | <p>The problem in this investigation was to determine the stress and
deflection patterns of a thick cantilever plate at various angles
of sweepback.</p>
<p>The plate was tested at angles of sweepback of zero, twenty,
forty, and sixty degrees under uniform shear load at the tip,
uniformly distributed load and torsional loading.</p>
<p>For all angles of sweep and for all types of loading the area
of critical stress is near the intersection of the root and trailing
edge. Stresses near the leading edge at the root decreased rapidly
with increase in angle of sweep for all types of loading. In the
outer portion of the plate near the trailing edge the stresses due
to the uniform shear and the uniformly distributed load did not vary
for angles of sweep up to forty degrees. For the uniform shear and
the uniformly distributed loads for all angles of sweep the area in
which end effect is pronounced extends from the root to approximately
three quarters of a chord length outboard of a line perpendicular to
the axis of the plate through the trailing edge root. In case of
uniform shear and uniformly distributed loads the deflections near
the edge at seventy-five per cent semi-span decreased with increase
in angle of sweep. Deflections near the trailing edge under the
same loading conditions increased with increase in angle of sweep
for small angles and then decreased at the higher angles of sweep.
The maximum deflection due to torsional loading increased with
increase in angle of sweep.</p>
