Descriptive geometry
Is a mathematical-graphical procedure that has for its purpose the visualization of structures and their exact representation in drawings. After analysic of any structure, each element is shown in the drawing in its exact geometrical...

Rate of doing work: power
In practice, where work is done upon a body, both the amount of work and also the time during which that work is done are important. For example, if a motordriven soist has to raise its load quikly, a more powerful hoist and a larger driving...
