Hi, here i need to calculate the tilt angle of the scissor lift. I had done some reviews for designing a scissor lifter, some source state that, tip-over will happen only when the kinetic energy of the system is less than the Potential energy after impact. Hence, i was trying to use this relation to find out the range of the best angle. But, i don't know how to calculate the Kinetic Energy of the whole system. Can anyone give me some idea to solve it?Thankyou in advance!!
