This simple screw jack is based around a bench-mounted base incorporating a turntable fitted with a metric square pitch screw jack thread. The apparatus is stood on a firm bench and a cord is wound around the periphery of the turntable. The free end of the cord is threaded over a pulley and then hangs vertically to accept the load hanger supplied.
A set of calibrated weights is supplied which are suspended from the load hanger thus producing a known torque on the system. To adjust the experimental parameters further the calibrated weights can also be applied to the top surface of the turntable.
A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
