7. Two vectors of unequal magnitude can never add to give the zero vector. However, three vectors of unequal magnitude can add to give the zero vector. If their geometric sum using the tail-to-tip method gives a closed triangle, then the vector sum will be zero. See the diagram, in ...
Bicycle set-up dimensions and cycling kinematic data are important components of bicycle fitting and cyclist testing protocols. However, there are no guide
Material point It`s a body which dimensions can be neglected under given conditions. Absolutely solid is defined as a system of particles interconnected by such Newtonian forces, which leave the distance between any two particles of this body unchanged. Absolutely elastic body is called the body,...

The concepts of coordinate transformations and kinematics in three-dimensions are the same as in two dimensions, however, the mathematics is more complicated. Furthermore, many of us find it difficult to visualize three-dimensional motion when all we are shown are two-dimensional representations of ...
We take the spherical four-bar linkage as our first case of study, as depicted in Fig. 1, with its four linkage dimensions noted by αj14. The two grounded revolute joints are labeled B and D, their position vectors being denoted by the unit vectors b and d. The two moving revolute ...
We also quantified the accompanying sex-specific mus- culoskeletal and reproductive volumes and dimensions. The hypothesis tested was that none of the locomotor differences would be present in the juvenile cohort i.e., the sexual dimorphism in locomotor performance would develop concomitantly with ...
We propose that the fault blocks were deformed in a ductile regime in a top-to-the NW-directed shear zone, leading to the non-cylindrical geometry of the Jungfrau syncline. Such over- turned half-graben limbs of metric to decametric dimensions are also observed at elevations of 2500 and ...
The influence of the drying element's dimensions is shown in an experimental model made with clay and sand. Among the results, two curves are particularly interesting: one translates the correlation between the initial dimensions of the drying elements and the final mean crack spacing, and another...
