Parts of a diaphragm include: [2] the collector (or membrane), used as a shear panel to carry in-plane shear; The drag strut member, used to transfer the load to the shear walls or frames; the chord, used to resist the tension and compression forces that develop in the diaphragm since the collector is usually incapable of handling these loads alone
The Block 2 (RIM-116C) is an upgraded version of the RAM missile aimed at more effectively countering more maneuverable anti-ship missiles through a four-axis independent control actuator system, increased rocket motor capability to 6.25–inch diameter, an improved passive radio frequency seeker and upgraded components of the infrared seeker ...
In early airships which relied on nets, fabric bands, or complicated systems of rope rigging to unite the lifting envelope with the other parts of the ship, semi-rigid construction was able to achieve improvements in weight, aerodynamic, and structural performance. The boundary between semi-rigid and non-rigid airships is vague. Especially with ...
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically.
Diaphragm (optics), a stop in the light path of a lens, having an aperture that regulates the amount of light that passes; Diaphragm (acoustics), a thin, semi-rigid membrane that vibrates to produce or transmit sound waves; Diaphragm (birth control), a small rubber dome placed in the vagina to wall off the cervix, thus preventing sperm from ...
A computer-aided design system was developed in 1969 for the McDonnell Douglas F-15 Eagle, which first flew in 1974 alongside the Grumman F-14 Tomcat and both used boron fiber composites in the tails; less expensive carbon fiber reinforced polymer were used for wing skins on the McDonnell Douglas AV-8B Harrier II, F/A-18 Hornet and Northrop ...
A classification for the structural system of a high-rise was introduced in 1969 by Fazlur Khan and was extended to incorporate interior and exterior structures. The primary lateral load-resisting system defines if a structural system is an interior or exterior one. [2] The following interior structures are possible: Hinged frame; Rigid frame
In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure, or as a device that vibrates when certain frequencies are applied to it.
