Finding angular velocity of a rotating bar using energy methods about pin - Method 1
The bar is purely rotating about the pin support, so if we view the bar as rotating around the pin, then the translational component of the kinetic energy will be 0 (because the pin is not moving). The change in gravitational potential...

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...

What is the formula for a unit vector from a vector in component form
In this video series I will show you how to find the unit vector when given a vector in component form and as a linear combination. A unit vector is simply a vector with the same direction but with a magnitude of 1 and an initial point...
