The common magnolia tree (Magnolia grandiflora), which is sometimes referred to as Southern magnolia, is hardy in U.S. Department of Agriculture plant hardiness zones 7 through 9. Common magnolias are prized by home gardeners for their evergreen foliage and fragrant, showy blooms, but their roots are also distinctive.he way that the roots curl as they grow can make magnolia roots prone to girdling if the roots circle close to the treeâs trunk. Magnolia roots are also close to the soil surface, with the majority of them within the top foot of soil.
Definition of MOMENT OF A FORCE. 1. of a point: the product of the distance from the point to the point of application of the force and the component of the force perpendicular to the line of the distance.
Any concurrent set of forces, not in equilibrium, can be put into a state of equilibrium by a single force. This force is called the Equilibrant. It is equal in magnitude, opposite in sense and co-linear with the resultant. When this force is added to the force system, the sum of all of the forces is equal to zero. A non-concurrent or a parallel force system can actually be in equilibrium with respect to all of the forces, but not be in equilibrium with respect to moments.
