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.

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.

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...

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...

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.

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.

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...
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 the following steps of this solution for me?

Mainly how they got their initial conditions? The 7.30 equation is just h[n-m] = bm which doesn't help me much.
For our problem, I know that n=3 and m =1 since the LHS...
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...
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...
