Triangular Plate
Problem Description
[1] we want to
change the values
of
W
and
R
to
reduce the amount
of material.
[2] The initial value
of the width of the
bridge is 30 mm and
its allowable range is
20-30 mm.
[3] The initial value of the
radius of the ﬁllet is 10 mm
and its allowable range is
5-15 mm.
