Your client asks you to construct a mobile accent for his house. You use an iron wite, 0.75m long and 2.75x10^-3 cm^2 in cross-sectional area and hang a brass cube of mass 8kg on one end. On the bottom of the brass cube, you attach a similar iron wire and hang another brass cube of mass 7.5kg. If young’s modulus elasticity for iron is 21x10^10Pa and that the weight of the iton wires is neglected. For the wire above, determine; A. Tensile stress B. Tensile strain C. Elongation
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
