See all →- What is the principle of transmissibility of a force and what are its limits? In one line A force acting on a rigid body can be slid anywhere along its own line of action without changing its external effect on the bod... 1
- How are force systems classified into coplanar, concurrent, parallel and non-coplanar types? In one line A force system is classified by whether the forces lie in one plane and whether their lines of action meet at a point or are par... 1
- How do you resolve a force into components and combine two forces into a resultant? In one line Resolution splits one force into perpendicular parts; composition combines several forces into one equivalent force called the r... 1
- How do you find the resultant of a coplanar concurrent force system by the method of resolution? In one line Add up all horizontal components and all vertical components separately; these two sums give the size and direction of the singl... 1
- How do you find the magnitude and position of the resultant of coplanar parallel forces? In one line The resultant of parallel forces equals their algebraic sum, and its position is found by making its moment equal to the total m... 1
- How is the resultant of a general coplanar (non-concurrent) force system found and located? In one line Find the resultant's magnitude and direction from Σ F_x and Σ F_y , then locate its line of action using Σ M about a point. Expl... 1
