Answer:
Explanation:
To find the expression for the position x of the particle as a function of time t you need to integrate the expression for acceleration two times. To find the integral constants you are already given the initial conditions for both the position and the velocity which are:
The first integration gives you the velocity:
You get the constant by using the second initial condition:
To get the expression for the position you need to integrate again:
where using the first initial condition.
You can now plot the graph. To get the total distance travelled you can integrate the expression for the velocity twice and sum the two integrals (from 0 to 1 and from 1 to 3):
20 m
Answer:
Explanation:
Given that
p V = 100
This is the isothermal process.
We know that non-flow work given as
We know that work for isothermal process
For isothermal process
Here C= 100
Negative sign indicates that work in done on the system.
Answer:
a) 280MPa
b) -100MPa
c) -0.35
d) 380 MPa
Explanation:
GIVEN DATA:
mean stress
stress amplitude
a)
--------------1
-----------2
solving 1 and 2 equation we get
b)
c)
stress ratio
d)magnitude of stress range
= 280 -(-100) = 380 MPa
