Answer:
Explanation:
Given that
Vrms= 60 V
Vf= 0.7 V
We know that peak value of AC voltage given as
Now by putting the values
The output voltage of the DC current given as
Therefore output voltage of the DC current is 84.15 V.
Answer:
fracture will occur as the value is less than E/10 (= 22.5)
Explanation:
If the maximum strength at tip Is greater than theoretical fracture strength value then fracture will occur and if the maximum strength is lower than theoretical fracture strength then no fracture will occur.
= 15 GPa
fracture will occur as the value is less than E/10 = 22.5
Answer:
For a new constructed building, causes of cracks and building failure are;
- permeability of concrete
- poor construction practices
- poor structural design and specifications
Explanation:
Cracks on buildings start when stress in components exceeds its strength. The externally applied forces that cause cracks on structures are : dead forces, live forces, seismic forces or forces on the foundation settlement. Internally forces that cause cracks include variation on temperatures, moisture content changes and chemical actions. Measuring and monitoring movements of cracks can be done through; using tell-tale, using a crack width gauge and use of precision calipers.
Answer:
Blank wall
Explanation:
A wall that cannot be moved because it is carrying the weight of the roof is considered a blank wall.
