Question

For safety reasons, a worker’s eye travel time in a certain operation must be separated from the manual elements that follow. The distance the worker’s eyes must travel is 20 in. The perpendicular distance from her eyes to the line of travel is 24 in. No refocus is required. What is the MTM-1 normal time in TMUs that should be allowed for the eye travel element?

Answer 1

Answer:

The answer is 12.67 TMU

Explanation:

Recall that,

worker’s eyes travel  distance must be = 20 in.

The perpendicular distance from her eyes to the line of travel is =24 in

What is the MTM-1 normal time in TMUs that should be allowed for the eye travel element = ?

Now,

We solve for the given problem.

Eye travel is = 15.2 * T/D

=15.2 * 20 in/24 in

so,

= 12.67 TMU

Therefore, the MTM -1 of normal time that should be allowed for the eye  travel element is = 12.67 TMU
