Biofuels - Both biodiesel and renewable diesel can be produced from plant or animal oils, fats, and wastes. According to the U. S. Energy Information Administration, the United States uses a combination of oils and fats in biodiesel production: soy oil 65%, corn oil 7.5%, and yellow grease and white grease was less than 8% of production of 8,478 million pounds of feedstock inputs for biodiesel in 2013. According to the latest published life-cycle analysis for various feedstocks and the feedstock mix reported by the Energy Information Administration and the U. S. EPA for 2013, the average GHG reduction for biomass-based diesel exceeds 80%. If biofuels provided a quarter of transport fuel in 2050, it would avoid an estimated 2.1 gigatons of GHG emissions per year. Although biofuels are among the few fuels for medium- and heavy-duty trucking that are considered renewable, there are some issues regarding its status as a sustainable fuel source. The sustainability of biofuels comes into question on several fronts. All BUT ONE is a reason why environmentalists question biofuels as sustainable energy resources.

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
