Deflection and translation of a ray traversing an optical system, nodal rays and the optical axis
Expressions are derived for the deflection and transverse translation of a ray as it traverses an arbitrary optical system. The system may be astigmatic and have relatively decentred refracting elements.

Deflection of concrete slabs with GFRP reinforcement caused by shrinkage
The use of new reinforcing materials and products in the construction industry requires their thorough assessment for a variety of design situations. One of the significant effects is the shrinkage of the concrete, which in the case of asymmetrically ...

Free vibration of rectangular plates with a small initial curvature [PDF]
The method of matched asymptotic expansions is used to solve the transverse free vibration of a slightly curved, thin rectangular plate. Analytical results for natural frequencies and mode shapes are presented in the limit when the dimensionless bending ...

Spin Rate and Deflection Ratio of a Ping Pong Ball
To investigate the effects of a spherical object’s spin rate on the curvature of its flight, Ping Pong balls, of varying spin rates, were hit horizontally and recorded from above with a high-speed camera.

Flight-measured X-24A lifting body control surface hinge moments and correlation with wind tunnel predictions [PDF]
Control-surface hinge-moment measurements obtained in the X-24A lifting body flight-test program are compared with results from wind-tunnel tests. The effects of variations in angle of attack, angle of sideslip, rudder bias, rudder deflection, upper-flap

Stress Analysis of Guide Rails of Elevators
The mechanical design of elevator elements is always performed by international standards. The engineer selects the appropriate elements of elevator according to catalogues without knowing scientific details. Therefore, a theoretical analysis is achieved
