attached file is a complete mechanism for turning over a sheet metal. i tried to use motion study to analyse the forces and torques but something is wrong. the motion analysis has not been complete yet. so far i used two rotary motors: one for lifting the frame and the other one for moving the slider-crank mechanism. the point is that i want the first motor to stop and the second motor starts working but as you see when the second motor starts working the first one still running although i turned it off with a key point in the time line.
anyone can fix it?
your help will be highly appreciated.
