28.Suppose that two hand trips are installed on a clutch-activated,part revolution press,the trips being incapable of triggering a brake to interrupt a stroke mid-cycle.If the flywheel speed is 120 rpm,calculate the safety distance for the two-hand trips.
29.A manufacturing engineer is considering purchase of a mechanical,full revolution,punch press for a high-efficiency workstation.You are asked to compute an appropriate safety distance for a two-hand trip safeguarding device for this machine.
a.What additional design specifications for this machine would you need
before responding to the manufacturing engineer's problem?
number of engagement points
b.What would be your response? (You may assume any arbitrary value(s)for data you listed in part (a)above as necessary to solve this problem. )
