Question: Problem 3.63 A fuel pump is driven by a motor-powered flywheel. The pump behaves as a spring with stiffness 2 N/mm that is unstretched
Problem 3.63 A fuel pump is driven by a motor-powered flywheel. The pump behaves as a spring with stiffness 2 N/mm that is unstretched when a = 60. Neglect any possible dynamic ef- fects. (a) Determine the largest tensile and compressive forces spring AB experiences during one revolution of the flywheel, and state the positions a where these occur. (b) Without further analysis, is it certain that the largest tensile and compressive forces in crank arm BC occur at the same positions a determined in Part (a)? Explain. 60 mm fuel pump 20 mm Awww D B crank arm Figure P3.63 flywheel
