Answer: There was 5/8 of a foot of board left.
Step-by-step explanation:
Step 1. We need to subtract 1/4 from 7/8. To do this make it where both fractions have the same denominator.
Step 2. The easiest way to do this is to multiply 1/4 by 2.
1/4*2/2=2/8.
Step 3. Now all you got to do is subtract 2/8 from 7/8.
7/8-2/8= 5/8.
Based off of the notes I have, the answer is True
Answer:
Since stress is greater than ultimate strength, the wire will break.
Step-by-step explanation:
The titanium wire is experimenting an axial load. Ultimate strength equals
. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress (
), measured in pascals, in the wire with circular cross-section is:
(1)
Where:
- Axial force, measured in newtons.
- Cross-section diameter, measured in meters.
Please notice that axial force is the weight of the man hanging from wire.
If we know that
and
, then the axial stress experimented by the titanium wire is:


Since stress is greater than ultimate strength, the wire will break.
