Since the deflection is proportional to the square of the applied voltage, both ac and dc voltages can be measured by using this instrument. As the instrument exhibits square law response, the scale is crowded (or compressed) at its lower end and hence, the scale is non-uniform. ...
WebOne of the most common examples of torsion in engineering design is the power generated by transmission shafts. We can quickly understand how twist generates power just by doing a simple dimensional analysis.Power is measured in the unit of Watts [W], and 1 W = 1 N m s-1.At the outset of this section, we noted that torque was a twisting couple, which … WebTherefore, deflecting torque acting on coil = either force x DK = n B I l x b cosθ= n BI A cosθ. Where A = l x b is the area of the coil. If k is the restoring torque per unit twist for the material of the suspension wire, then restoring torque = kθ. Since in equilibrium, the restoring torque is just equal and opposite the the deflecting ...
