I would like some help with the first part of this problem. I have calculated the distributed load to be 3.82kN down as the integral of f(x) from 0 to 6 gave me that value. I found it to be 3m to the right of A as well. As such based on an analysis beam ABCD I calculated A(y) to be 3.67kN...

Please help me in understanding the history of physics regarding the atomic or non-atomic, say continous, structure of physics. In my years at school I grew up with physics of ultimate simplifications. Everything was a point "particle", like the moon revolving around the earth. Like the apple...

How are the poles of a tapered magnet distributed? Is there any way to calculate its magnetic force?

Hello, Forces can be concentrated (when acting at a single point) or distributed (when acting over a surface or line). In the case of distributed forces, we can find the resultant concentrated force by calculating a surface or line integral of the force density ##f(x)## w.r.t. an area or length...

Hello, I'm reading FLP vol II, and I would appreciate some help to understand the argument supporting Figure 6-6. Basically they claim if a sphere has non-uniform charge distribution whose surface density is proportional to the cosine of polar angle, then this surface charge distribution is...

Hi guys, I'm wasting much time on this problem but still can't manage to get to a solution; I'll attach my attempt below. I started with drawing the FBD of the beam "sectioned" at point C, in order to find an expression for the internal shear force at that point and then equal that to zero...

I have a series of variables X i where ultimately the variables Xi each follow approximately an exponential distribution with a constant rate. In the beginning, there is a certain long-term trend. Is there a probability model in which Xi depends on the outcome of Xi-1 so that in the long run...

I've found part (i) by calculating the z-score for 40 $$Z = \frac {40- 50} {15} = -0.67$$ $$N(-0.67) = 1- N(0.67) $$ $$1- N(0.67) = 1-0.7486 = 0.2514$$ But parts (ii) and (iii) are confusing me. I have answers provided by my professor that say the mean and std deviation for (ii) and (iii) are...

Hi, I have this question: If random variable T is uniformly distributed over [a, b] , what is its failure rate? Please help

1) ##P(X>0.5)=P(Z>0)=0.5## 2) ##P(0.45<X<0.55)=P(X<0.55)-P(X<0.45)=P(Z<1)-P(Z<-1)\approx68\%## 3) ##P(X>x)=0.9\Leftrightarrow P(Z>\frac{x-0.5}{0.05})=0.9\Leftrightarrow1-P(Z\leq\frac{x-0.5}{0.05})=0.9\Leftrightarrow P(Z\leq\frac{x-0.5}{0.05})=0.1## I find that ##\frac{x-0.5}{0.05}=-1.28##, which...
