Answer:
The young tree, originally bent, has been brought into the vertical position by adjusting the three guy-wire tensions to AB = 7 lb, AC = 8 lb, and AD = 10 lb. Determine the force and moment reactions at the trunk base point O. Neglect the weight of the tree.
C and D are 3.1' from the y axis B and C are 5.4' away from the x axis and A has a height of 5.2'
Explanation:
See attached picture.
Answer:
42.69 N and 18.07 N
Explanation:
We are given that
Mass of ladder=6.2 kg
Length of ladder=1.97 m
Distance of Sawhorse A from one end=0.64 m
Distance of sawhorse B from other end=0.17 m
Let center of Ladder=
Now, the distance of sawhorse A from center=r=0.985-0.64=0.345 m
Distance of sawhorse B from center of ladder=0.985-0.17=0.815 m
Force one ladder due to gravity=mg=
Where
Torque applied on Sawhorse A=
Torque applied on Sawhorse B=
In equilibrium
Total force=
Answer:
Part a)
Part b)
Explanation:
As we know that magnetic flux through the loop is given as
now we have
now rate of change in flux is given as
now we know that
Now plug in all data
Part b)
Now the radius of the loop after t = 1 s
Now plug in data in above equation
Generally the metal of container is made up of such material that it will absorb heat and distribute it on the surface so that the temperature can rise and it will help to cook the food
But the handle of the container is used to hold it and we need not its temperature to be vary high so the handle must be made up of different material which will not absorb too much heat and its temperature will not rise to high value so that we can hold it easily
so here most appropriate option is given as
<em>D) The metal in the handle can absorb more energy without changing temperature as easily as the metal in the pot.</em>
