2.... Hydraulic controlled riveting assembly machine. hydraulic control system. Must include the following controls: Rotational control of the index table (150 lbs weight). Part clamps at each station . Rivet insertion station (guarded station not clearly shown - assume pick (up/down) and place (forward/return) motion, with rivet gripper control (grip/release). Drill station to attach the rivet. Total cycle should be 10 seconds.
how would that schematic look, and how would the speed, forces, and heat loss be calculated.
there were no other info given as far as flow rate, torque and things like that. where would you start?
Q1.
The lathe operates on the principle of..
