The elliptical exercise machine shown below has fixed axes of rotation at points A and E. Knowing that at the instant shown the flywheel AB has a constant angular velocity of 6 rad/s clockwise, determine the acceleration of point D. Solve this problem, then assuming the ease of starting the elliptical moving is proportional to the angular velocity (app) and using only the equations below plus geometry, how would you redesign the machine to minimize the effort needed to start the elliptical moving. Be sure to resolve the problem based on your redesign to show that the effort would be lowered and estimate the percent change in effort. QB = a₁ +ã XTB/A-W²TB/A VB = VA+WXTB/A

+ G In the above diagram, the wheel starts from rest and rolls without slipping. The force (you don't need the value) causes a constant angular acceleration of 7.112 rad/s2. The radius of the wheel is R - 0.392 m. What is the magnitude of the acceleration of the point at the top of the wheel at time t 1.400 s? This is the point at the outer edge directly above the center of gravity, Gwhere the force F connects to the wheel. Use units of m/s. Don't place units in your answer, 3 o
