The beam supports the distributed load shown. Determine the resultant internal loadings acting on the cross section at point D. Assume the reactions at the supports A and B are vertical.
ENED 1020: Engineering Foundations Final Handson Experiment Fuel Cell Car Lab Report Intro Electric cars have begun to storm the market in the past few years due to their being an effective and cleaner alternative to the nonrenewable resources we depend on. Fuel cell cars have also been considered an alternative, but have received less attention because of the lack of refueling stations for these novel vehicles. In this experiment, we look to explore the comparative efficiencies of electric and hydrogen powered cars. We will do this by using electricity to power a car to travel a distance of 15 feet, and then use electricity to produce hydrogen to power a car for 15 feet, and compare the amounts of power required in each case. Procedure 1. Retrieved the fuel cell kit 2. Measured and recorded the voltage and resistance supplied by the DC battery pack 3. Connected the battery pack to the vehicle chassis 4. Turned on the car and let it travel 15 feet, recording the time it took to travel this distance 5. Measured the voltage and resistance supplied by the AC outlet 6. Set up the electrolyzer to collect hydrogen Figure 1: Set up to collect hydrogen 7. Collected 25cm of hydrogen using an AC outlet to power the electrolyzer and recorded the time taken to collect this hydrogen 8. Hooked up the fuel cell and hydrogen storage tank to supply power to the vehicle chassis
