On an elliptical machine, the linkage connects the rotating flywheel to the reciprocating handles. If the flywheel is rotating at deltadelta.deltadelta rad/s, determine the velocity of the tread in the position shown. The blue line connects the pivot points of the tread support, there is a separation of 15" and an angle of 23 degrees from horizontal. The red distance from the handle pivot to the tread support is 19" vertical. The green connection from the flywheel center to the tread support is 6" aligned 30 degrees from the vertical. The tread is located by the pink line 9" from the back pivot at an angle 10 degrees from the blue line.
