Case Study: The Bay Area Rapid Transit
This document is a case study of the Bay Area Rapid Transit (BART) system, focusing on the ethical issues faced by three engineers who raised safety concerns about the train’s automatic control system. The document analyzes the responsibilities, rights, and violations of the engineers, the management, and the engineering organization (IEEE) in relation to the BART project. The document also suggests some actions to avoid such violations in the future and to promote a culture of ethical enginee...

DESIGN AND ANALYSIS OF A SPEED REDUCER GEARBOX & PULLEY-BELT SYSTEM
It is required to design a speed reduction system consists of a driving-driven pulley belt system and an inline gearset to reduce a motor velocity (system input velocity) ω_i= 2250 rpm to output velocity ω_o= 150 rpm. The transmitted power P= 15 hp is reserved throughout the system components (friction losses are negligible). The system is to be operated under uniform load and occasional moderate socks continuously for 8 hours/ day, 5 days/ week, for 8 years. The system is to have minimal siz...

Machine Design: SHAFT DESIGN
The rotating solid steel shaft is simply supported by bearings at points “B1” and “B2” and is driven by a motor. The shaft transmits a torque T to a gear (not shown) which meshes with the spur gear “G”, which has a pitch diameter D. The force F from the drive gear acts at a pressure angle of 20°. The shaft operates at a speed of Ω rpm. The minimum allowable distance between the shaft and the bearing is a. Using an appropriate factor of safety, design a shaft that has a minimum ...
