It is desirable to be able to describe an automobile mathematically
because of the large number of variables which affect automobiles'
handling characteristics and of the high cost of building prototypes.
A mathematical analysis facilitates the construction of a
few prototypes whose configurations look most promising.
Equations of motion were...
This paper investigates a particular bridge construction technique
which could result in a significant torsional moment. The
structural member under consideration is a prestressed concrete
girder for which no torsional consideration is made.
Torsional shear stresses can be adequately approximated for
an I-shaped girder. Laboratory model tests were performed to...
