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 cord moves on the pulley without slipping or stretching. Therefore pulley rotates as the masses movr. The pulley has mass and therefore the pulley has moment of inertia. There must be net torque which is responsible for starting the rotation of the pulley. The net torque is resultant of two torques due to the two cords. Tensions in left and right cords are NOT EQUAl Tension in right cord is more because of the heavier mass of block B.
