Hertz (Hz)

Following are the main characteristics of simple harmonic motion: In simple harmonic motion, **the acceleration of the particle is directly proportional to its displacement and directed towards its mean position**. The total energy of the particle exhibiting simple harmonic motion is conserved. SHM is a periodic motion.

**The motion of a simple pendulum** is an example of simple harmonic motion.

Difference between Periodic and Simple Harmonic Motion**In the periodic motion, the displacement of the object may or may not be in the direction of the restoring force.** In the simple harmonic motion, the displacement of the object is always in the opposite direction of the restoring force.

Hertz (Hz)

The time for one oscillation is the period T. The number of oscillations per unit time is the frequency f. These quantities are related by **f=1T f = 1 T** .

**Find the acceleration from the equation representing the displacement and try to relate**. The other method is that an SHM usually involves conservation of energy. So try finding total energy. If it is constant, then look for spring like properties, which we usually find in an SHM.

Linear simple harmonic motion (S.H.M.) is defined as the linear periodic motion of a body, in which the restoring force (or acceleration) is always directed towards the mean position and its magnitude is directly proportional to the displacement from the mean position. Concept: Linear Simple Harmonic Motion (S.H.M.)

**The pendulum oscillating back and forth from the mean position** is an example of simple harmonic motion. Bungee Jumping is an example of simple harmonic motion. The jumper oscillating up and down is undergoing SHM due to the elasticity of the bungee cord.

**Write the equation of SHM for the situations show below:**

- A=Asin(ϕ)⇒sinϕ=1:Hence,ϕ=π/2.
- -A=Asin(ϕ)⇒cosϕ=1:Hence,ϕ=3π2.
- A2=Asin(ϕ)⇒sinϕ=12,Hence,ϕ=π6,5π6.

Velocity in SHM

When we substitute equation II in equation I, we get, **v(dv/dx) = – ω ^{2} x**.

**x ( t ) = A cos ( ω t + ϕ )** . This is the generalized equation for SHM where t is the time measured in seconds, ω is the angular frequency with units of inverse seconds, A is the amplitude measured in meters or centimeters, and ϕ is the phase shift measured in radians (Figure 15.8).

Machine Design is **the process of selection of the material, shape, size and arrangement of mechanical element so that the machine will perform its task**. A process which includes design of all parts of machine subjected to carry the forces without failure by transforming other form of energy into mechanical energy.
