) Suggest a forming process and illustrate how to mass produce pins from a very long rod. Label each component and show any motion with an arrow. b) Calculate the initial rod length to form one complete pin. c) Determine if the pin head can be formed on this machine with a single stroke. Why

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
