Best Way to Solve Statics Problems

wahaj

My question is very simple. When solving static equilibrium problems (such as finding reactions at joints) when should I take the moment about the x,y, and z axes and when is it better to take a joint and find the reaction forces on that joint? Also any other tips will be appreciated.

You'll probably have to use moments and force balances in combination; if you have 3 unknown variables for example you'll need three equations relating them, and odds are one or even two will be moment balances.
