Worker element a b e (min) (0.90) (154) (2.46)
Worker element a b e (min) (0.90) (154) (2.46) (348) Machine element d (min) (225) The continuous timing method was used to obtain the times for a worker-machine task. Only on cycle was timed. The observed time data are recorded in the table above. Elements a, b, c, and e are worker- controlled elements Element d is machine controlled. Elements a, b, and e are external to the machine- controlled elements, while element is internal There are no irregular elements. All worker-controlled elements were performance rated at 70% The PFD allowance is 10% and the machine allowance is 15% Determine the standard time for the cycle Select one 2.79 minutes 2.68 minutes 2.50 minutes 3:07 minutes
