    Comp Sci The Longest Increasing Sequence in a Two-Dimensional Grid of Numbers

    The problem with your code is that it checks to see if there is a number that it can jump to, then it jumps there. When it does the first jump to the next square it can't continue to check the other surrounding squares. Your function should eliminate the impossible moves, then call itself for...

    Bending and deflection of composite beam

    I guess you'll have to determine where the neutral axis or centroid is in the cross section, this will be skewed towards the material with the higher young's modulus. then to determine I, you can determine I for each of the parts of the cross section then use the parallel axis theorem to...

    Calculate Maximum Bending Moments & Stress

    If you want us to help us, you need to show us what you have done to attempt the question. Because you haven't done that, I'll just ask a question. Where will the maximum bending moment and therefore maximum stress occur on the see-saw?

    Master Shear Force Diagrams with this Helpful Homework Example

    That is now correct, you can check your answer here, http://learntoengineer.com/beam?f=2,u1|8,u2|3,-10|10,-20&d=0,10!-5&m= The SFD does have to go back down to 0 at the end. The shear force and bending moment of any beam is 0 at a free end.

    What is the true value of money in a competitive society?

    I plotted the amount of money I had in my bank account on one graph and my general happiness on another and found that they were directly proportional to each other. but seriously, money is what I steal from other people. sorry couldn't resist. Money is something that allows me to...

    High School Does a Seat Belt Increase Risk of Injury in a Car Crash?

    I would doubt it. however if it does cause most deaths in accidents I would bet it prevents more deaths than it causes and that without the seat belt, the people would have died anyway in most cases.

    What is the Number of Einstein's Students?

    Take X as the total number of students: X*(1/2 + 1/3 + 1/7) + 20 = X Then use your algebra.

    Possible webpage title: Styling Text and Tables in HTML/CSS

    I'm guessing that all of these questions are about html/css mainly because of the table cells question. You need a bit more information in your question, and show us how you have gone about searching for the answer.

    Electricity current question , nodes

    We aren't supposed to just give you the answer. You have multiple power sources, so start by using the superposition method which means looking at one source at a time and then adding them all up at the end. Once you've started with that if you need any help, don't hesitate to ask for more.

    Shear force with a mirrored triangular load

    The reason you cannot take the moments about A like you have and determine the shear force diagram is because at the section you cut the beam (D), there is a bending moment equal to some value (46Nm courtesy of http://learntoengineer.com/beam?f=0,u1|18,u2&d=0,9!-2/9*x|9,18!-4_2/9*x&m= ) because...

    Graduate Can You See a Parallel Universe Through a Black Hole?

    doesn't sound real. It is likely a 'theory' based on no scientific data (ie a guess or something someone would like to be real)

    Graduate Is our universe finite or infinite?

    if an object has 'nothing' around it then it cannot be observed to be traveling at any speed because there are no observers. The car in your example surrounded by nothing could be stationary or traveling, the people inside the car would not even know. The only way you can tell that you or...

    Mom sues preschool for damaging 4 yo Ivy League chances

    seriously this mother is an idiot? preschool is a place for kids to play not learn calculus. if she is pushing her kid that hard, it's likely that the kid will become alienated from other people forced to study. this does not necessarily mean the kid will become smart.

    Calculating the Steady State Value of Vc After Opening a Switch in a RC Circuit

    It doesn't look like you've attempted the solution. but I'll give you some tips. when the system is in a steady state the capacitor acts as an open circuit (ie: all the current goes through the 1k resistor.) what is the voltage across the 1k resistor at steady state: 1x10^3 x 10x10^-3 what...

    Is fixing car alignment important?

    If your car is veering heavily to one side, then you might need more than a simple alignment which could get more costly. But car safety is one of the most important things when you are on the road, always keep your car in good running condition.
