21 hours ago · This paper discusses the optimal control law, in a three-dimensional (3D) heliocentric orbit transfer, of a spacecraft whose primary propulsion system is a Solar Wind Ion Focusing Thruster (SWIFT). A SWIFT is an interesting concept of a propellantless thruster, proposed ten years ago by Gemmer and Mazzoleni, which deflects, collects, and accelerates the charged particles of solar wind to ...
Coplanar force systems have all the forces acting in in one plane. They may be concurrent, parallel, non-concurrent or non-parallel. All of these systems can be resolved by using graphic statics or algebra.
Sep 25, 2023 · A coplanar force system can be defined as, “A group of forces acting on an object is called a coplanar system of forces if the line of action of all the forces lies in the same plane.” In most engineering problems, we deal with the analysis of objects acted upon by a coplanar system of forces.
Jan 5, 2019 · This chapter focuses on coplanar forces acting at a point. When all forces are acting in the same plane, they are called coplanar whereas when forces act at the same time and at the same point, they are called concurrent/forces.
A force system is said to be concurrent, if the lines of all forces intersect at a common point (Fig above). A force system is said to be coplanar, if the lines of the action of all forces lie in one plane (Fig below). Resultant of a system of forces acting on a rigid body
When the lines of action of these forces lie within the same plane, the system is known as a coplanar force system. All these forces can be resolved into their respective components using cartesian vector form.
When the lines of action of all the forces of a system act along the same line, this force system is called collinear force system. Fig.2.3 Force System 2.3.2 Parallel Forces
