Technical Description
The central element of this unit is a vertical spindle nut combined with a metric thread. A specific torque can be exercised on the spindle thread using a rotating plate designed as pulley. For this purpose a mechanical spring balance and a nylon cord are included with the unit. Additional weights that can be placed on the plate to enable the axial loading on the thread to be changed. The efficiency of the thread can be determined from the measured values. The portable apparatus is designed for table-top experiments and is equipped with anti-slip feet. Clips are fitted to base plate for all the individual parts.
Learning Objectives / Experiments
· Determination of the mechanical advantage of a spindle
· Determination of the efficiency of the thread
