The sudomotor test is done with the use of two hand electrodes & 2 feet electrodes as a stand alone test or in conjunction with ANS testing.Stimulation of sweat production is measured by the change in humidity for a period of 2 minutes.he sudomotor test is done with the use of two hand electrodes & 2 feet electrodes as a stand alone test or in conjunction with ANS testing.
Using the example above. If the load is lifted 2 metres, above the pulley wheel-the rope on the right hand side must be shortened by one metre and this also applies to the left hand side. Therefore, the effort can be seen to move twice as far as the load. A pulley system with the effort applied from above is very difficult to use. The most comfortable way to use a single moving pulley is combine it with a fixed pulley, seen below.
Torque demand, expressed in foot-pounds, is the result of force (line pull) x radius (distance from the drum axis to the outer layer of wire rope). If the line pull remains the same, and the number of layers on the drum increases, the torque required to lift the load (torque demand) increases. For example, assume the line pull resulting from a load on the hook is 16,000 pounds. The radius to the first layer of wire rope is 25-l/2â³ -:- 2, or 12-3/4â³. Torque required to rotate the drum, equals 17,000 foot pounds (i.e., 16,000 x 12.75 -:- 12).
