Is that what the blue lines are for? I actually don't know how to graph something properly using MasteringEngineering. One of my previous answers did not have the vertical blue line at 4.75, but had everything else the same and that was marked incorrect for me as well.

http://img687.imageshack.us/img687/5889/shear.png I'm having trouble drawing the shear diagram on MAsteringEngineering. I'm pretty sure the values are correct too? I got By = 10.5 and Ay = 9.5 V(x) = -2x+9.5 for the distributed load so when I set V=0, I find the x intercept to be...

Hello, I was wondering if someone could explain part of the solution to this problem for me. http://img706.imageshack.us/img706/5517/disksproblem.png To the right is the Free Body Diagram of Disk E, and I can draw the forces on there well enough. But I really do not understand how they...

http://imageshack.us/a/img842/2497/112639506.jpg Calculate the resultant force’s magnitude and the couple moment. Let a = 3.70 m w1=5.35kN/m w2=4.00kN/m The resultant force of the triangle is 1/2(3.70)(5.35)=9.898 kN The resultant force of the rectangle is (4)(3.70) = 14.8kN So...

Sorry about that Rank the items from smallest to largest. To rank items as equivalent, overlap them. I shall also edit my post

Statics Problem:Distributed Loads http://imageshack.us/a/img845/5825/112639502.jpg When measuring from the left side of the beam Xa,Xb ,Xc ,Xd ,Xe ,and Xf are the locations where the resultant force is applied in each of the six cases. Rank these six locations. Rank the items from...

http://img831.imageshack.us/img831/8005/f48am.jpg Determine the magnitude of the resultant moment produced by the forces about point O Determine the direction of the resultant moment produced by the forces about point O I first break the forces down to their components. F1x =...

Determine the magnitude of the resultant force FR. Assume that F1 = 230 and F2 = 395 Express your answer to three significant figures and include the appropriate units. Determine the direction of the resultant force FR , measured counterclockwise from the positive x axis. I got the...

Let A, B, and C be sets. Show that a) (A-B) - C \subseteq A - C b) (B-A) \cup (C-A) = (B \cup C) - A I am using variable x to represent an element. Part A) I rewrote (A-B) - C as (x\inA ^ x\notinB) - C I think this could be rewritten as (x\inA ^ x\notinB) ^ x\notin C A-C can...

For Part A, the index for the final answer is m = 0 though. You have it at m=1 for (-2)m

It's been a while since I took Calc 2 and I am in a Linear Systems and Signals class right now. I'm looking at a solution on how to obtain a zero state response of a discrete time signal, but performing the summation confuses me. Can someone explain the steps they did? This is part A...

Can someone explain the steps of this solution? In my linear systems class, we are doing Laplace transforms using transform tables and the properties. I can usually do the problems that closely resemble the table, but when they involve heavy algebraic manipulations, I don't know what to do...

http://img215.imageshack.us/i/unledc.jpg/ Using the residue method, I found K1 and K2 to be -2 and 4 respectively. However, where do I go from there?

I try solving using node equations I make a node called V1 where the three resistors intersect each other and another node called VL above the inductor The node equation for V1 is (V1-60)/30 + V1/60 + (V1-VL)/20 = 0 V1/30 - 2 + V1/60 + V1/20 - VL/20 = 0 The node equation for VL is...
