Vf2 F2

With Varignon's theorem, the magnitude of moment M may then be calculated from

with d, and d2 defined as the moment arms in Fig. 3.6c. Note that the direction of the

moment would be determined by the sign of Eq. (3.9); with a right-hand convention, positive would be a counterclockwise and negative a clockwise rotation.

This force and moment could further be used to compute the line of action of the resultant of the forces F1 and F2 (Fig. 3.6d). The moment arm d could be calculated as

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
