So x would be where the force is on the beam? So if the force was in the center, and the beam was 50 ft(600in) long, then x = 300in!? F (force)= 6,000lbs E (Modulus of elasticity) = 29,000,000 I (Moment of inertia) = 850 L (length) = 600 in So if I understand this right, then this would...

What is x.. I don't get it. I understand everything else except for x. Help!?

What's the L mean?! And the 48? Does the length of the beam have no place in the calculation? So \delta = (PL^3)/(48EI) would be: 6000^3 / 48 x 29,000,000 x 850^4 = 0.000000000297261601 ?

I'm not sure the formula to use to calculate the deflection of a beam. Here's the information I have got. Steel beam is 50 feet long. There is a 6,000 pound load in the middle(all other loads are disregarded. The modulus of elasticity is 29,000,000 psi. Moment of inertia is 850 inches^4...

So for this x, y chart thing, it'd go something like... [center] | x | y | | 0 | -2| | 2 | 4 | | 4 | 7 | | 5 | 13| And then the second question is kinda like reversing it?? And the / was like and/or type thing. Sorry about that. So either one of those ones could be the one with a...

Also, I am asked to pick out which table represents a relation that is NOT a function. A. Input Value | +9 | 4 | 16 | 32 Output value|-18 | 8 | 32 | 64 B. Input Value | 0 |1/-1|2/-2| 3 Output value| 0 | + 1 | +2 | 9 C. Input Value | -2 | -1 | 0 | 1 Output value| +4 | +2 | 0| -2...

How do you... Draw the graph of y=3x-2 on the grid. Identify at least two points on the graph by their coordinate pairs. Anybody get that?? It's one of those x,y axis grid thingers. And there's a table under it with 8 columns and 2 rows. Kinda like...

Ready Reckoner?? Does anyone know what a ready reckoner is and what its purpose is?? Mathematically speaking. It asks me a question about this on my work sheet, but nowhere in the textbook nor in the booklets, does it state what the hell this thing is. Thanx

Simple Question..?? A mover pushes a 260-kg piano on wheels up a ramp 7.0 m long onto a stage 1.75 m above the auditorium floor. The mover pushes the piano with a force of 680-N a) How much work is done by the mover? b) What is the work done on the piano by the machine? Help...

Have you heard about the new movie staring the fabulously talented Mary-Kate and Ashley Olsen? Also the very comedic Eugene Levy? It's called New York Minute, an action/comedy coming soon to a theater near you! Check out this AWESOME site!

Thanks for the help cookiemonster...

..whoops...yeah, a sphere. How do you find the diameter of a sphere using the volume?

Simple Question: Volume --> Diameter I know how to find volume using diameter, but how do you find diameter using volume?

Wow.. I never saw that. Thanx

It's like a riddle thinger.. If 9 times 9 is 7 10 times 9 is 9 10 times 8 is 8 8 time 8 is 2 What is 9 times 7 ? It says to "Think mathematically. There is a pattern of calculating involved." Anybody got any idea what this is? What the answer is??
