I decided to use the lagrangian to get the differential equation in the generalized coordinate θ to obtain its differential equation. I've got this
(I0+Icr)θ'' + (mgLcosθ)θ' = 0
Icr is the moment of inertia of the second rod with respect to its instantaneus center of rotation.
Ok so I solved...
Homework Statement
Hi, I've been trying to solve this exercise for the last four hours and I'm totally stuck. The problems goes like this:
Given the mechanism in the image, located in the vertical plane, the OB cord is cut when t=0. Find the reactions Rx, Ry and N in {Kgf} for the instants...
Well, for someone that has only seen first semester of calculus class i guess that big deal for me!.
I have seen integration by parts, but i never made the connection. Makes a lot of sense i guess.
I was actually trying to find a way to define the integral as a limit not involving sums of...
i tried with functions such as x^2 and x^3 and it works perfectly, i don't know how to attack sums involving e^k or 1/n. But the idea is solid, i tried it for definite and indefinite integral and its working. I tried to integrate f(x)=ln(x) using its derivative but i i can't get past the 1/n sum.
I think i discovered a new way to define an integral, i don't know if it helps in any particular case, but its an idea worth posting i think.
The idea is to define the height of the rectangles based on one single point of the function and then build up the next heights for the other rectangles...
