Optimized Sythesis of a Force Generating Planar Four-Bar Mechanism Including Dynamic Effects
… allows for the matching of the entire resistance curve by approximately matching a set of positions that define the shape of the curve. This work furthers the discipline of mechanism design by combining dynamics into existing linkage synthesis methods, resulting in an improved synthesis method …

Kinematics of beam flexure four-bar linkages with applications in a compound bow
… and the bow mechanics to provide a resistance curve that is more compatible with the human strength curve. In addition, by modifying the bow kinematics, more potential energy can be stored, and thus potentially more kinetic energy can be transferred to the arrow than with previous bows.

Design and testing of a nonlinear mechanical advantage demonstration mechanism
… points are chosen from the flexion/ extension strength curve of the forearm. Unlike most strength training equipment, this linkage exploits unused muscular capability by allowing variable resistance. Users are capable of dramatic increases in maximum resistance and efficiency over constant …

Studying water-wedging as a cause for short term overheating in the boiler of a coal-fired power plant
… equivalent stresses, was compared to the yield strength of the material. A temperature vs yield strength curve was obtained from material testing using new and aged tube material. The results showed that short term overheating at the superheater outlet tubes due to water blockages alone is …

A Comparison of Strength and Resistance Curves for the Internal and External Rotators of the Shoulder.
… is important for proper rehabilitation of muscle strength, yet varies across types of resistance for a given exercise. The purpose of this study was to compare strength curves (SC) for shoulder internal (IR) and external rotation (ER) with resistance curves (RC) for two application angles (A and …

Factors Influencing the Post-Earthquake Shear Strength
… behavior of these materials. Moreover, if strength loss as a result of cyclic loading were to occur in the material comprising the dam and/or dam foundation, the consequences of failure could be substantial. The objective of this study is to evaluate the effect of plasticity …

Three-dimensional modeling of failure in quasi-brittle materials and structures
… calculate the load capacity, or structural strength, of structures while taking into account the nonlinearity of the material behavior and the consideration of realistic boundary conditions such as geometry, size, and loading configuration. The main objective of this study is to develop …

A Shapely Resistance: A Study in Construction for a Kindergarten
… deals with the relationship between form and strength in architecture. The proposed building is a Kindergarten which unites issues of shape, physics, and habitat. The roof is vaulted and the walls are curved for lateral resistance and in order to make folds scaled to a child. These physical …
