Web16 mrt. 2024 · Let four force F 1, F 2, F 3 and F 4 acting at a point O making angles θ 1, θ 2, θ 3 and θ 4 with the X-axis respectively. Let R be the resultant force acting at angle θ with the X-axis. Resolving the forces along the X-axis, i.e. horizontally, we get ΣF x = F 1 cos θ 1 – F 2 cos θ 2 – F 3 cos θ 3 + F 4 cos θ 4 WebThe main types of forces that you will meet can be divided into contact and non-contact forces. Non-contact forces – allow remote parts of the environment to affect an object: …

WebA force can be graphically represented by a straight line with an arrow, in which the length of the line is proportional to the magnitude of the force and the arrowhead indicates its direction. A force system is said to be concurrent, if the lines of all forces intersect at a common point (Fig). A force system is said to be coplanar, if the ...
