Study on Crankshaft Failure: A Review
Abstract: Crankshafts are power shafts of engines with a complex geometry having crankwebs and crankpins. Crankshafts axis is offset from the centre. It converts the linear (reciprocating) motion of pistons into a rotary motion that can be transmitted through a drive line system. A crankshaft is subjected to several forces that vary in magnitude and direction (multiaxial loading). Bending stress and shear stress due to twisting are also common stresses acting …

Review on Photoconductive Antenna Design from Conventional to Microstructures
Abstract: Semiconductors possess many diverse phenomena under terahertz-frequency electromagnetic radiation (THz). This is due to the fact that the energy of THz photons is at quite large scales in case of bulk and low-dimensional materials and devices. With regard to broadband THz sources, various inorganic crystals such as ZnTe/GaP/GaAs/GaSe/DAST/LiNbO3 have been used which are pumped by femtosecond laser pulses. These pulses are combined with field-resolved detection through electro-optic sampling using similar …
