Let$$s go back to our scaffold problem but now the scaffold has a mass of

$100$kg and is initially held in static equilibrium but then the left hand wire

is cut. What is the tension in the right wire and angular acceleration?

Also the centroid of the scaffold occurs at L

$2$ and the IG $=$ mL$2$

$12.$ The length

of the beam is $10$m and the linear acceleration is $5$ m$2$

s at the center of

mass
