About This Product
The screw efficiency experiment belongs to mechanics practicals on simple machines. Students apply an effort through the cord and pulleys, record it against the load, and work out mechanical advantage, velocity ratio and efficiency. T.P.I. means threads per inch and describes the pitch of the screw. A wall bracket keeps the apparatus rigid during the readings, and weights have to be arranged separately.
