APPLICATIONS To design the structure for supporting a water tank, we will need to know the weights of the tank and water as well as the locations where the resultant forces representing these distributed loads are acting. How can we determine these weights and their locations?

APPLICATIONS (continued) One concern about a sport utility vehicle (SUVs) is that it might tip over while taking a sharp turn. One of the important factors in determining its stability is the SUV’s center of mass . Should it be higher or lower for making a SUV more stable? How do you determine its location?

CONCEPT OF CG and CM The center of gravity (G) is a point which locates the resultant weight of a system of particles or body. From the definition of a resultant force, the sum of moments due to individual particle weight about any point is the same as the moment due to the resultant weight located at G. For the figure above, try taking moments about A and B. Also, note that the sum of moments due to the individual particle’s weights about point G is equal to zero. Similarly, the center of mass is a point which locates the resultant mass of a system of particles or body. Generally, its location is the same as that of G. 3m 4N 1m A B 1 N 3 N G
