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

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

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
