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.

For a very every case the moment of inertia of a one particle about an axis is given by, I = mr 2 Here, m is the mass of the particle and r its distance from the axis under
An equiconvex lens has the radius of one curved surface is 0.12 m and focal length of 0.10 m. Determine the refractive index of the material of the convex lens.
When the curve is not simple or linear as diode valve is known as non-ohmic device.
Steel: Steel contains iron with a small percentage of carbon added it. Iron itself is not very strong but the additions of small percentage of carbon in it decrease the ductility
