Analyzing Vibrations in a Long Mast

Report describes mathematical prediction and measurement of vibrations in light weight extensible mast of lattice structure. With mast suspended from 10 vertical wires, vibrations excited in horizontal plane by motor-driven mechanism or by hand. Vibrations recorded photographically and with accelerometers.

Characterizing Shear Properties of Membranes

Method devised to obtain static shear stiffness data for membranes. Shear deflection of membrane measured under various applied static shear loads, and measurements plotted. Match attempted between experimental plot and predicted load-vs.-deflections curves until best fitting theoretical curve is found.
