solve problem 9-33 (page 388) in hibbeler 8th edition. determine the slope and displacement at point b. ei is constant. use the method of virtual work. 15



Answer :

The slope and displacement at point b. ei is constant. By using the method of virtual work we get Triangle B=6637.5 / EI.

The study of forces and movement in a mechanical system results in virtual work when the concept of least action is applied. A force's work on a particle as it moves along a displacement varies depending on the displacement. One will minimise the action among all virtual displacements, or potential displacements, that a particle might take. As a result, the particle follows this displacement in accordance with the principle of least action. The term "virtual work" refers to the labour performed by a force on a particle along a fictitious displacement.

virtual work and the associated calculus of variations were initially created to examine systems of rigid bodies, but they were later developed for the study of mechanics.
