Answer:
The distance between the two objects.
Explanation:
Answer:
31677.2 lb
Explanation:
mass of hammer (m) = 3.7 lb
initial velocity (u) = 5.8 ft/s
final velocity (v) = 0
time (t) = 0.00068 s
acceleration due to gravity (g) 32 ft/s^{2}
force = m x ( a + g )
where
- m is the mass = 3.7 lb
- g is the acceleration due to gravity = 32 ft/s^{2}
- a is the acceleration of the hammer
from v = u + at
a = (v-u)/ t
a = (0-5.8)/0.00068 = -8529.4 ( the negative sign showa the its decelerating)
we can substitute all required values into force= m x (a+g)
force = 3.7 x (8529.4 + 32) = 31677.2 lb
I think that the answe is gasses.
Answer:
Explanation:
As we know that the moment of area of polar is also known as the second moment of area. It is used to describe resistance to torsional deformation, on cylindrical objects with an invariant cross section area.
Therefore, mathematically second moment of area can be written as,
Here, R is the radius of circular cross section.
Given that a circular section is welded to a wall has a diameter,
Therefore,
Therefore, second moment of area for the circular weld pattern is,
