Construction
A free body diagram, an FBD, is not meant to be a scaled drawing. Rather it is a working sketch open to modification as one works through the problem and typically one needs to have seen through the problem before one arrives at a satisfactory diagram. There is an element of art, an inherent flexibility in the whole process. There is no hard and fast algorithm. The iconography of a free body diagram - not only how it is drawn but also how it is interpreted - depends crucially on how a body is modelled.

Famous quotes containing the word construction:
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“There’s no art
To find the mind’s construction in the face.”
—William Shakespeare (1564–1616)
“The construction of life is at present in the power of facts far more than convictions.”
—Walter Benjamin (1892–1940)
