You guys always act like hot stuff. Let's see if you can do an easy problem:
"A beam with length 'l' is carried by 3 men, with one man at one end and the other two supporting the beam between them on a crosspiece placed so that the load is evenly divided among the three men. Where do you place the crosspiece, neglecting the mass of the crosspiece and giving your answer as a distance from the free end of the beam?"
