The sign has a mass of 100 kg with center of mass at g. determine the x, y, z components of reaction at the ball-and-socket joint a and the tension in wires bc and bd.

First, one must draw a picture or have access to a diagram. Then, one may utilize a list of force and momentum equations. With this list, one will create five equations with five variables: Ax, Ay, Az, bc (C), and bd (D). The list of equations can be entered into a scientific calculator in the form of a matrix and the variables can be solved for. The equations will look like: 4C+2D+0+0+0=981N -2C+4D+0+0+0=0 C-2D+Ax+0+0=0 -2D-2C+0+Ay+0=0 2C+D+0+0+Az=981N Ax=0, Ay=589N, Az=490N bc=294N, bd=589N

Idon't know it i just need my points lol
