First, the geometrical parameters of the system R, d, L, p , the angular velocity and the number of rotations for 1 have to be introduced see Fig.. Then, the vertical coordinates and the velocity of the point A are calculated and plotted.
An animation of the mechanism is performed see Fig.. The mechanical system is shown in different congurations when the solid 1 turns around the Oz axis. Rolling trolley see Fig.. It is assumed that there is no sliding at the contact points M, N et P see Fig..
Motion of 1 depending on the reference frame s. With s as a reference, we note that MN denes the instantaneous axis of rotation for the motion of 1. Motion of 1 depending on the reference frame. After having introduced the numerical parameters for this exercise radius of the balls and the velocity of the trolley , the relative velocity of point O depending on the reference frame s or are computed and displayed on the screen.
The gear set is dened by the two wheels s centre O, radius R and centre C, radius r , the wheel s being xed. If the velocity! The number of degrees of freedom can be determined quite directly see Fig.. The rst one is used to calculate the speed of P depending on the reference frames as function of the numerical parameters introduced by the user: the radii r and R and the angular velocity!. The scalar product of the velocity of P and the vector MP is also computed to show that they are perpendicular.
The amplitude of the velocity is plotted when the rod makes a complete revolution around O. To set things clear, we have, in terms of motion: ffl arotationof 1 with respect to s, ffl a rotation with respect to 3 and a pure rolling without sliding of on 1, ffl a translation of 3 with respect to s. We ask to determine v C3 as a function of!
For the following parameters:! One can notice that the pure rolling without sliding introduces two constraints: zero normal and tangential velocities. After giving the two radius r 1,r and the angular velocity! In the current state, the rod OA and the horizontal axis X dene an angle ff, the rod AB being vertical and the segment BC being horizontal. Projection along the Y axis:!
First, the geometrical parameters of the system R, d, L, p , and the angular velocity of 1 have to be introduced. First, the geometrical parameters of the system r,!
Then, the user need to choose between a representation of the velocity vector or the acceleration vector during the wheel motion. We suppose in this exercise that, the angular acceleration of the body is constant. For such a motion to occur, the wind w should blow in the backward face of the sail.
If ff is the angle between the longitudinal axis and the wind direction and fl the angle between the longitudinal axis and the sail orientation see Fig.. The le Kex7. According to the Eq.. The points A, B, C and D being clearly located by the gure: 1.
In the conguration represented at Fig.. Considering as parameters of the system! The two velocity vectors and their projection on the AB axis are represented. It was an effective trick. We learned a lot working with the tool and building it as it was being used. Book Sprints were short events building books collaboratively. So Booki was meant to be all about collaboration. Booki also was run as a website booki. Many groups used it which was cool.
We also experimented with data visualisations of book production processes. We did some cool stuff with the visualisations.
They had a huge window that you could backwards project onto so people could see the projections on the street.
So we made a visualisation of text from the book being overlayed as we wrote it. Below is an image shot with us standing in front of the projector…I mean.. You could enter the target URL of a book from another install and Booki 1 would make a portable archive booki.
Booki 2 then unpacked the zip and populated the book structure complete with images etc. I liked the idea very much of using EPUB instead as a transport technology instead and was later able to do so for Aperta and PubSweet 1 see below. I think the only stuff that went further than the previous system was the dynamic table of contents plus it was easier to install and maintain.
It was in some ways just a slightly different version of the previous system. Booki was also used for producing a tonne of books.
Objavi is basically a separate code base that was used as a file conversion workhorse. Objavi 1 was a little bit of a hacky maze but it did a good job. It would basically accept a request and then pipe that through a preset conversion pipeline.
It did a good job. What I found most useful from this is that each step left a dir that I could open in a browser to inspect the conversion results. Objavi 2 was meant to be an abstraction.
I always thought internalising file conversion was a bad idea because file conversion is resource-intensive, making it better to throw it out to another external service.
And having a separate conversion engine enables you to completely overhaul the book production code without changing the conversion code.
This was a HUGE advantage. All content would be passed through Objavi for import and export so Objavi became the obvious conduit for passing a book from one system to another. This gave me a lot of ideas about federated publishing which I have written about elsewhere and archived here. Point A is on the outer edge of the tire at the forward position that is level with the wheel's center at the end of this 2 seconds.
The radius of the tire is 13 inches 0. The wheel has an inner hub and an outer hub. The radius of the inner hub is 6 inches and the radius of the outer hub is 18 inches. The velocity and acceleration of the surface touching the inner hub is 0. Find the angular velocity and acceleration of the wheel and the velocity and acceleration of the wheel's center at this instant. Also, the pin at B slides in the slot of bar CD. Determine the angular velocity and angular acceleration of bar CD at this instant.
Each cup has an occupancy limit of three riders.
The cups are rotated with respect to the platform by the riders through a wheel at the center of the teacup. The platform itself is turned by a large electric motor. Use your knowledge of dynamics to address the following issues; a it is desired that the sustained acceleration of a rider should be less than 3g and b the peak acceleration experienced by a rider should be less than 5g. Note: There may be information that you need to complete your design which you do not have.
