Hey there people,
I will be starting my junior year in the mechanical engineering department, and they say is the hardest one throughout the 4 years, I will be taking Fluid Mechanics, Theory of Machines 1, Machine Elements 1, Heat transfer , Principles of economics, Numerical methods, and...

The Attempt at a SolutionI solved exactly the same as in the solution manual, except for the FBD of the slider B, when they write the 2nd Law, they do not input the weight there, only the...
Homework Statement
Which of the series, diverge or converge ∑ 5^n/(4^n +3 )
Homework Equations
The Attempt at a Solution Taking the limit as n→∞ we have (5^n ln 5)/ (4^n ln 4) , my question is here how does it become like this, which part am I missing here?
We are using Dynamics by Kraige, I saw the Hibberler book too and it looked better to me.If you have information about both of them, which one would you suggest it to me?
The semester will start on Monday, and I am planning to have the Kinematics chapters finished before it has started...
Hello everybody,
Last semester I took dynamics and I got FD, and luckily the course is going to open in the summer school too.So I am trying to pass the course in the summer school, why not getting a good grade too.
Reasons why I did not pass were mainly because I did not like the teacher (...
Integrating what I've written above, I got 1/2(v2^2-(10)^2= 300 , and going further v2=square root of 700. I just have to find how does the curve or line of velocity changes with position.
Homework Statement
The a-s graph given below belongs to a bus traveling along a straight road.Given that the velocity of the bus is 10 m/s when s=0, plot the v-s graph of the bus.
Homework Equations
∫vdv=∫ads or 1/2(v2^2-v1^1)=(area under a-s curve.

Oh, yes. So that means I am correct. But, looks like I have not solved the question I was asked, instead, I have solved another question without the moment given.
I inverted the beam in order to have the x-y system of coordinates with x positive - horizontal to the right , and y - positive...
Homework Statement For the beam shown in the figure: a) Draw necessary free body diagrams
b) Calculate support reactions
c) Draw the shear force and bending moments
Homework Equations
∑Fy = 0; ∑M = 0; V(x) = ∫ L(x) ; M(x) = ∫ V(x)

Okay, I got it. Fs = mu * N, and also Fs T * cos theta , I found N and then put it into the equations got the correct result for mu. So, in this question we did not need to write FBD for the shaft, because I could not solve it in that way, using components of the force was much easier. Thank you...
Okay, I think I got the correct result now, my angle is 70.5 deg and the tensile force in each cord is, T = 26 N. I think this is correct. But, still in the FBD of shaft my forces are cancelling each other. About leaving a space character between sentences I am trying to do it every time, but I...
Homework Statement The 5-kg cylinder is suspended from two equal length cords. The end of each cord is attached to a ring of negligible mass that passes along a horizontal shaft. If the rings can be separated by the greatest distance d= 400 mm and still support the cylinder, determine the the...
