question 64

Multiple Choice

Table 9.23
The Terminal Company is attempting to balance its assembly line of high-voltage electrical connectors. The desired output for the line is 50 connectors per hour, and the information on the work elements for this assembly line is as follows.
 Work  Elements  Time  (sec)   Immediate  Predecessor(s)  A40B36 AC20 AD2 AE30 B,CF34DG35EH5 FI15E,HJ40HK38G,I,J\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Work } \\\text { Elements }\end{array} & \begin{array} { c } \text { Time } \\\text { (sec) }\end{array} & \begin{array} { c } \text { Immediate } \\\text { Predecessor(s) }\end{array} \\\hline \mathrm { A } & 40 & - \cdot \\\mathrm { B } & 36 & \mathrm {~A} \\\mathrm { C } & 20 & \mathrm {~A} \\\mathrm { D } & 2 & \mathrm {~A} \\\mathrm { E } & 30 & \mathrm {~B} , \mathrm { C } \\\mathrm { F } & 34 & \mathrm { D } \\\mathrm { G } & 35 & \mathrm { E } \\\mathrm { H } & 5 & \mathrm {~F} \\\mathrm { I } & 15 & \mathrm { E } , \mathrm { H } \\\mathrm { J } & 40 & \mathrm { H } \\\mathrm { K } & 38 & \mathrm { G } , \mathrm { I } , \mathrm { J } \\\hline\end{array}
-Use the information from Table 9.23,and the longest work-element rule to balance this line.If the time needed to perform work element K was reduced by 1 second and all other work element times were unchanged,what would happen to the number of stations needed to balance the line?
