Spatial ability, such as the ability to correctly visualize three dimensional objects when they are represented in two dimensions (such as in computer-aided design (CAD) software or in a detailed part drawing), is an essential skill for engineers. Research has shown that spatial ability is positively correlated with retention and performance of students within other disciplines which rely on spatial...
This paper highlights areas of inaccuracy in current modelling techniques for bridge decks with wide cantilevers. A 3-D grillage model known as the upstand grillage is assessed by comparing its behaviour with that of a three-dimensional finite-element model. Recommendations are made for the implementation of such a technique. The paper concludes with a comparison of results from analyses of a bridge...
The strongest myosin-related features in the low-angle axial x-ray diffraction pattern of resting frog sartorius muscle are the meridional reflections corresponding to axial spacings of 21.4 and 14.3 nm, and the first layer line, at a spacing 42.9 nm. During tetanus the intensities of the first layer line and the 21.4-nm meridional decrease by 62 and 80% respectively, but, when the muscle is fresh,...
