SOME PROBLEMS ON MACHINE DESIGN
Machine Design is defined as the use of imagination, scientific principles and engineering techniques to create a machine or structure economically, in order to satisfy the requirements of a customer. Machine design is the first step involved in creation of a machine. It gives the basic idea of how a machine will look and function.

snr curve
Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. SNR, bandwidth, and channel capacity of a communication channel are connected by the Shannon–Hartley theorem.
cotter joints
Cotter joint is used to connect two rods subjected to axial tensile or compressive loads. It is not suitable to connect rotating shafts which transmit torque. Axes of the rods to be joined should be collinear. There is no relative angular movement between rods. Cotter joint is widely used to connect the piston rod and crosshead of a steam engine, as a joint between the piston rod and the tailor pump rod, foundation bolt etc
