Engineering Mechanics

Engineering Mechanics is the science which considers the effects of forces on rigid bodies. The subject is divided into two parts.

  1. Statics – the effects and distribution of force on rigid bodies which are and remain at rest.
  2. Dynamics – consider the motion of rigid bodies caused by the forces acting upon them.

Force System – a force system

– is any arrangement where two or more forces act on a body or on a group of related bodies

Resultant of Concurrent Forces in Space

Engineering Mechanics

Example:
Given the three concurrent forces which through (1, -3, 4) and the indicated points
F1 = 150N (5, -6, 2)
F2 = 340N (4, 0, -3)
F3 = 280N (-1, 2, 6)

Determine the magnitude of resultant force.

Solution: Resolution of Forces
