looks very simple and should be solvable with access to basic physics formulas

1. a cylindrical beam of length L and mass M hanging out from a awall and suspended by a rope as shown

find:
a - the torque about the axis indicated exerted by the rope and by gravity on the beam (recall that graivty can be taken to act at the center of mass of the beam, which herei s the center)
b - the tension in the rope

now suppose that the string breaks

c- how fast is the end of the rod going when it hits the wall?

Here's the answers at least...

a. Throw rope over center of beam. Run the 'tail' of rope R through a fixed loop on the end of that same rope. Apply to neck.
b. Tension=mass (less if you've only been eating Top Ramen for a month)
c. When mass=mB swings into the wall with force
v=v0+at where a=BB/100 and t=3k hands then neck will snap with force f=mB X a.
