sir, if the motion has been through the fastener arrangement or the rotary motion is used to get the linear motion. then how do we have to calculate the velocity and distance nd speeed as well as accelaraion? e.g. in a screw and nut arrangement. if i apply the moment of torque/force. the screw is to be traversed from one pich to other then how tho calculate the kinetic energy involved in it. and also the velocity with which it moves etc.
