Unformatted text preview: Assuming no air resistance and no friction in the mechanism, at what speed will it impact the workpiece? How much energy does the hammer have? A slider-crank mechanical punch has a stroke of 50 cm. The length of the link is 1.6 m. Assume the crank can supply 1400 Nm of torque. a. Plot the potential force at the ram as a function of crank angle. (Note: At TDC and BDC the force will go to infinity, so only plot forces up to +/- 10,000 N.) Homework #2 Fundamentals of Production Engineering EML 6324 – Fall 2012 (5.) b. c. Page 5 of 6 Plot the forces (again up to 10,000 N) as a function of ram position on the downstroke. Plot the ram position as a function of crank angle. Homework #2 Fundamentals of Production Engineering EML 6324 – Fall 2012 (5.) d. e. Page 6 of 6 If it takes one second to complete a stroke, plot velocity as a function of crank angle. Plot velocity as a function of ram position. Homework #2...
