When the component simple harmonic motions have dissimilar periodic times:
The resultant curve may be attained in this case by dividing the circumferences of the two circles of reference into parts in the ratio of the periodic times, so that the projections of the parts on respective diameters give the displacements because of the individual simple harmonic motions in equal intervals of time.
- The slope of the tangent drawn on the U versus X graph provides us the value of the restoring force acting on the block.
- The graph can be used to attain the value of PE stored in the spring at any stage.
Necessity Of A Starter For D.C Motors When motor is at rest, then N=0 and due to Eb is directly proportional to N, so At begin E b = zero Thus armature current at t
