PROBLEM 3: POWER AND EFFICIENCY PLEASE HELP ME WITH MY ASSIGNMENT - Solve the problems on a clean sheet of paper. Follow the Given-Required-Analysis-Solution-Summary of Answers format. Make sure to include all pertinent solutions. - Round your final answers to three (3) decimal places. For example, if you calculated an answer to be “9.80665” it should be expressed as “9.807”. At the instant shown, point P on the cable has a velocity vp = 12 m/s which is increasing at a rate of ap=6m/s2. Determine the power input of motor M at this instant if it operates with an efficiency of 0.8. The mass of block A is 50 kg.
2. Thermal Efficiency a. Planet Express Generating Station in New York, NY uses 8720 Btu of energy to generate each kilowatt hour of electricity. Find its thermal efficiency. Express as a percentage with no decimal point. b. Mystery Shack Generating Station in Gravity Falls, OR has a thermal efficiency of 43%. How many million cubic feet (MMcf) of natural gas are needed to generate 560 megawatt hours of electricity? Round to the nearest hundredth.
Type in your answer/s rounded off to 2 decimal places except for whole numbers. (ex: 10.67, 28, 732.40) If your answer is 120.00 kN, just write 120 kN Do not round off values during solving. Use the store function of your calculator or its fraction if applicable. Include the units after your answer. Leave a space between the value and the unit. (ex: 6323.17 m, 73.10 rad/s^2, 100 kN) For stresses, type (C) for compression and (T) for tension one space after the unit. (ex: 18.19 MPa (C), 6.88 psi (T))
