Answer: maximum "safe" Force = 415.58 N
Step-by-step explanation:
<u>Length = 1.2 m</u>
lower bound is 1.15 (because it rounds up to 1.2)
upper bound is 1.24 (because it rounds down to 1.2)
<em>Note: 1.25 would round up to 1.3</em>
<u>width = 2.5 m</u>
lower bound is 2.45 (because it rounds up to 2.5)
upper bound is 2.54 (because it rounds down to 2.5)
<em>Note: 2.55 would round up to 2.6</em>
<u>Pressure = 150 N/m²</u>
lower bound is 147.5 (because it rounds up to 150)
upper bound is 152.4 (because it rounds down to 150)
<em>Note: 152.5 would round up to 155</em>
<u>Max "safe" Force means minimum Area and minimum Pressure (lower bounds)</u>
Force = Area x Pressure
= length x width x Pressure
= 1.15 x 2.45 x 147.5
= 415.58
