Explanation:
Value of the cross-sectional area is as follows.
A = 
= 3.45 
The given data is as follows.
Allowable stress = 14,500 psi
Shear stress = 7100 psi
Now, we will calculate maximum load from allowable stress as follows.
= 
= 50025 lb
Now, maximum load from shear stress is as follows.
= 
= 48990 lb
Hence, 
will be calculated as follows.
= 48990 lb
Thus, we can conclude that the maximum permissible load is 48990 lb.
Answer:
energy required=-energy lost
energy lost=change in kinetic energy
EL=1/2 mv^2
Yes, As a result, wool is positively charged while polythene is negatively charged. As a result, 1.87 1012 electrons have been transported from wool to polythene. As a result, only a sliver of mass is transferred from wool to polythene.
Physical change changes the form of a chemical substance
According to the conservation of energy
- Potential energy at any given instance is equal to the Kinetic energy as energy can neither be created nor be destroyed
Mass is 2kg=m
#A
h=5m
PE
Now
- KE=98J
- 1/2mv²=98J
- 1/2×2v²=98J
- v²=98J
- v=√98
- v=9.4m/s
#B
h=3.2m
PE:-
Now
- KE=62.7J
- 1/2mv²=62.7
- v²=62.7
- v=√62.7
- v=7.9m/s
#C
h=2m
PE
Now
