Statics Formula Sheet
Static Equilibrium: F = ma = 0 (for static objects that aren't accelerating M = I_G alpha = 0 (for static objects that don't have an angular acceleration). Notice that moments can also be written as a vector using M = r x F. Note that...

Basic statics problem finding reactions of pin supports
This video shows how to find the magnitudes of reaction forces of pins. A general approach to this question is to 1) draw a FBD 2) use Mtotal = 0 and Ftotal =0 3) solve the algebra. A few things to note are: Pin supports apply external...

Reactions Example 1
Pin supports prevent movement in the x and y directions. This is why there are forces acting on the pin in the horizontal and vertical directions. Roller supports allow movement along one axis which is why there is only 1 force acting...
