It will be D. 168 because 7 times -4 = -28 then you times -28 with -6 and it equals 168.
Answer:
3220
Step-by-step explanation:
5x4=20
3x6=18
20+18=38
1=60
38x60=2280
20x25=500
2280+500=2780
6000-2780=3220
Answer:
The answer is 46.
Step-by-step explanation:
You have to substitute the value of a and c into the expression :
Let a = 10,
Let c = 4,
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.
