Statics: 3D Statics Problems



So far all that has been discussed is how to solve a two dimensional statics problem. However, in real life most problems are going to be 3d. To solve a 3d statics problem you would have to follow the same steps that you would used to solve a 2d statics problem, except in this case there is one more dimension that needs to be considered.

Also, when a problem is 3 dimensional it can have up to 6 possible statics equations to describe it. Those equations represent the summation of forces in the x, y, and z direction and the summation of moments around the x, y, and z axis. Refer to equations 1 through 6 below.

transverse force in the (statics equation) in the x direction (1)

transverse force in the (statics equation) in the y direction (2)

transverse force in the (statics equation) in the z direction (3)

moment statics equation around in the x axis (4)

moment statics equation around in the y axis (5)

moment statics equation around in the z axis (6)

Below is an example of a three dimensional statics problem and how to solve for the resultant forces.
