Your response gets me going in the right direction. I'll try what you mentioned and see what I turn up with. If I run into difficulties I'll look for further consultation. Thanks for leading me in the right direction. I was not exactly sure how to find the deflection occurring at C based upon...

Homework Equations
The following equations apply to a cantilevered beam held fixed on the left end:
\delta_{max} = -\frac{PL^3}{3EI}
\theta = -\frac{PL^2}{2EI}
\delta = \frac{P}{6EI}(x^3-3Lx^2)
The following equations apply to...
So your saying that the shear force does apply a shear stress at location A.
I have attached a graphic of how I have my reactions acting at point A. Looking at this I don't see how the shear force would apply a shear stress. In the equation for the shear stress by a shear force include a...
They get beta = 120 from the given angle of 60 degrees.
180 - 60 = 120 degrees
The 60 degrees is referancing from the top of the pulley. To change the referance point to the bottom of the second pulley they performed the above calculation.
Also, since their referance point is...
The equations of statics tie into your free body diagram by mathmatically describing the the situation dipicted in the diagram. Beause you are dealing with elements that are in a "static" state, this means that they are in equlibrium. This means that all the forces in the x-direction should have...
Homework Statement
For an element [Stress Block], determine the range of values of \tau_{xy} for which the maximum tensile stress is equal to or less than 60 MPa.
Given in the provided figure:
\sigma_x = -120 MPa
\sigma_y = -60 MPa
Homework Equations
\sigma_{ave} = \frac{\sigma_x...
Civil Major Here. I have enjoyed it so far. Choosing Structures as my focus has been difficult. I seem to have the hardest time with my structual classes. I really haven't gotten a feel for the other focus areas yet but I will be very soon. I have had a few advisors tell me I should switch to...
I am trying to find the frequency response for the given circuit.
My instructor recomended using a nodal analysis method. However, while attempting to use the nodal analysis I end up with all my variables equaling zero (Va = 0, Vin = 0 and Vout = 0). Is there something I'm missing or over...
Material Science (Chemistry Related) Problem
I am having a hard time starting my solution to the following problem:
So far I have been looking throughout the textbook at some sample problems but the sample problems are not asking for a similar solution to this question. I have also referred...
Could you possibly elaborate on where my error in my solution for Question 1 is, because I keep coming up with the same answer for q'. I re-solved the last equation 4 times and still result in the same answer.
On Question 2: How is it that I go about starting to show that there exists two...
The Following two questions are giving me the worst time. Maybe someone else can lead me in the right direction.
Question 1: You unconsciously estimate the distance to an object from the angle it subtends in your field of view. This angle \theta in radians is related to the linear height of...
