where Cm is a coefficient whose value is to be taken as follows:

1. For compression members with ends restrained from joint translation and not subject to transverse loading between supports, Cm = 0.6 - 0.4(Mj/M2), Mx is the smaller and M2 is the larger end moment in the unbraced length of the member. M1 /M2 is positive when the moments cause reverse curvature and negative when they cause single curvature.

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.
