yes, that helps me alot. Thank you very much.

I need help finding the equation for a 25ft cantilever beam deflection where the beam has an even distributed load of 3000 lbs/ft and also has concentrated loads of 4000lbs 8ft from the clamped end and 5000lbs 18ft from the clamped end. A generic equation from a Roark table would do, but I am...

thanks a lot, sorry about the difficulty you had while reading this. How do you right out the equations like you have it? I would like to be able to do that so my posts later on are more clear. Thanks again for your help.

[SOLVED] Volumes of Revolution Homework Statement find the volume of region A in the first quadrant that is inclosed in the parabola 2x(2-x) and the x-axis, of which is rotated around the axis y = -2. Homework Equations y=(4+2x^2) y= -2 piS(from 0 to 2) (R^2 - r^2) The Attempt at...

Homework Statement Your starship, the Aimless Wanderer, lands on the mysterious planet Mongo. As chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 11.0 returns to the ground in 9.00 ; the circumference of Mongo at the equator is...

Thanks. That helped me, I'm pretty sure I have it now.

Homework Statement To the right is the graph of 5x^3y-3xy^2+y^3=6. Verify that (1,2) is a point on the curve. There's a nearby point on the curve whose point is (1.07,u). What is the approx. value for u? There's a nearby point on the curve whose coordinates are (.98,v). What is the approx...

i think i finally got the answer to be 324.22pi by plugging in 40 to the above equation for C and then multipliing by delta x which in this case is 2

4pi(c/2pi)^2

after solving for the volume when the radius is (21/pi) which is a +2cm error i got the answer 1251.1cm^3. when i solved for the volume when the radius was (19/pi) a -2cm error i got 926.6cm^3. last i solved for the actual measured raius which was 40 and found the radius to be (20/pi) when i...

thanks, that actually helps me a lot.

[SOLVED] Linear approximation Homework Statement Juan measures the circumference C of a spherical ball at 40cm and computes the ball's volume V. Estimate the maximum possible error in V if the error in C is as most 2cm. Recall that C=2(pi)r and V=(4/3)pi(r) Homework Equations deltaf -...

Homework Statement Two curves intersect orthogonally when their tangent lines at each point of intersection are perpendicular. Suppose C is a positive number. The curves y=Cx^2 and y=(1/x^2) intersect twice. Find C so that the curves intersect orthogonally. For that value of C, sketch both...

haha i was just going to post this same problem
