Ergonomic injuries are caused by ergonomic risk factors like
awkward or sustained postures, strain, contact pressure, exposure to vibration
and exposure to heat or cold. Over time, a combination of these factors may
lead to injury, pain, and disability. Ergonomic injuries which can directly or
indirectly be related to work environment can affect the nerves, tissues,
muscles, tendons, and joints. For instance, on average, an employee may spend
about 6-8 hours on the computer.

symptoms that computer users may exhibit when they experience these musculoskeletal
disorders include pain in the shoulders, upper or lower back and the
neck. Others include discomfort when making certain movements, loss of
coordination, general feeling of cramping, weakness of muscle function, and a
sharp burning stabbing pain in the
wrists.</span>

Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
