Basic motion time systems quantify fundamental human motions in units equal to ten-thousandths of_______________?
Show answer Hide answer
Answer: B. minute
Explanation
Predetermined motion time systems quantify fundamental human motions in Time Measurement Units equal to ten-thousandths of an hour. One TMU is specifically defined as zero point zero zero zero zero six hours, which equals zero point zero zero zero six minutes. Standard industrial engineering practices use TMUs to establish consistent standard times for manual operations. Methods-Time Measurement breaks manual work down into basic elemental motions like reach, grasp, and move. Time Measurement Units provide a universal standard for comparing labor productivity across different manufacturing plants. Industrial engineers convert TMU values into seconds or minutes when scheduling assembly line workstations.
Manufacturing companies use basic motion time systems to optimize workstation layouts and balance production lines. Accurate labor standards improve cost estimation, pricing strategies, and worker performance evaluations. Ergonomic analysis benefits from breaking physical tasks down into fundamental human motion elements. Measuring units in ten-thousandths of a second would yield excessively small numbers for standard industrial motions. Measuring in minutes directly without ten-thousandth scaling contradicts the standard definition of Time Measurement Units. Hourly units require conversion multipliers, making minute-based base definitions the standard reference standard.
