Answer:
Amount of linear movement
Explanation:
Our system is defined by the rate of change in mass that
leaves the car , this happens during a time interval
, in addition to freight car and sand at time t.
In this way we need to define the two states:
State 1,
consider and V.
State 2,
consider
In this state is the mass of sand output, which
is composed of
In this way we define the Linear movement in x, like this:
In this way we proceed to obtain the Force
Since the mass of the second term becomes 0, the same term is eliminated, thus,
Answer:
d= 7.32 mm
Explanation:
Given that
E= 110 GPa
σ = 240 MPa
P= 6640 N
L= 370 mm
ΔL = 0.53
Area A= πr²
We know that elongation due to load given as
A= 42.14 mm²
πr² = 42.14 mm²
r=3.66 mm
diameter ,d= 2r
d= 7.32 mm
Answer:
The centripetal force increases.
Explanation:
Centripetal force is given by ; where
.
Given these two equations, we can rewrite the formula for centripetal force as:
As shown, radius is in the denominator, thus, a smaller radius would lead to a larger centripetal force.
