ABSTRACT The design of 2 tones automated hydraulic jack was carried out using the basic principles of machine design and analysis. The hydraulic jack was designed with a 204watts wiper motor with the output lever having a torque of 30Nm. The effective diameters of ram and plunger pistons were found to be 12mm and 6mm respectively, when the load lifted was 2000N with mechanical advantage being 3.4. The working stress was 21MPa when the effort applied at the handle by the lever was 594.3N. ...
ABSTRACT As Nigeria aims at optimizing the implementation of the E-learning programme in tertiary institutions, this paper discusses the ways by which the implemented E-learning can be sustained. The discussion was carried out using data derived from students, teaching staff and telecommunication engineers in Nigeria using Owerri metropolis as a case study. Data analysis was carried out and analyzed using excel and Minitab. Conclusions and recommendations were drawn for effective implementa...
