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.
The pulley is usually used in sets of two or more to gain a higher velocity ratio and mechanical advantage. Two sets of pulleys are used, one fixed and one moving. The pulleys are mounted, usually side by side, in a block or frame and the apparatus of pulleys and ropes is generally called the tackle. The whole system or machine is known as a block and tackle.
