Stress,Strain and Elasticity more different materials with forces applied along the lengths of the bars. In this context, ‘statically indeterminate’ simply means that the equations of static equilibrium are not sufficient to find the separate forces in each component of the compound bar.

Flow of Fluidse movement of liquids, pressures are developed. This means that stresses are generated in the materials being used and consequently design becomes the important aspect. Storage of liquids is another engineering problem; this will not be the concern in this section, but consideration of storage canno

Torsion of Circular PrismsWhen a shaft ., for example, from an engine to a gearbox, the drive shaft is always ., that is, a particular cross-section will have an angular displacement relative to all the other cross-sections. When the shaft ceases to transmit power the . is released, and the twist disappears.

Angular MotionAlthough the empirical laws laid down by Newton do not actually mention angular or rotational motion, the necessary ideas are contained in Newton’s laws of motion and it is worth repeating them here.
