Problem $4$: The snapback timing method was used to obtain average times for work elements in

one work cycle. The times are given in the table below. Element d is a machine$-$controlled element

and the time is constant. Elements a$,$ b$,$ c$,$ e$,$ and f are operator$-$controller and were performance

rated at $90\%$; however, elements e and f are performed during the machine$-$controlled element d$.$

The machine allowance is zero $($no extra time is added to the machine cycle$),$ and the PDF

allowance is $14\%.$ Determine $($a$)$ the normal time for the cycle and $($b$)$ the standard time for the

cycle.
