# Problem M. 347. (January 2015)

M. 347. Fix a wooden skewer to the rim of the table. Gradually load its free end, or hang a spring balance to it. Measure the torque $\displaystyle M$ needed to break the skewer, and the work $\displaystyle W$ done by the load. Will the measured data change if the length $\displaystyle \ell$ of that part of the skewer which sticks out of the table is halved?
