What is Ramp: Definition and 686 Discussions

RAMP (an acronym for Roy Ayers Music Productions) was an American soul/jazz band from Cincinnati, Ohio. It was founded in 1976 by Roy Ayers, who was not a member of the group, though he did write and produce songs on their only album. The band consisted of Sharon Matthews and Sibel Thrasher on vocals, Landy Shores on guitar, Nate White on bass, and John Manuel on drums and percussion. The band are joined in the present day by Kia Bennett and Desiree Jordan.
The group released one studio album, Come Into Knowledge, subsequently considered a classic among rare-groove collectors, artists (such as Erykah Badu, Mary J. Blige, Common, PM Dawn, A Tribe Called Quest and many others who have used RAMP samples in their music) and Roy Ayers fans.
Come Into Knowledge was recorded at Electric Lady Studios in New York City and at Record Plant in Hollywood, California. The group was a vehicle for the songwriting talents of Ayers and Edwin Birdsong. Released in 1977 via ABC Blue Thumb, the set featured a version of Ayers' "Everybody Loves the Sunshine" along with the 'rare groove' track "Daylight". The LP record release of the album commands very high prices. The album was eventually reissued and re-released on CD in 2007 by P-Vine Records in Japan and by Verve Records in Europe and the United States.The group split up shortly afterwards, but reformed in 2006 for new tours and recordings. RAMP performed on June 30, 2007, with Washington, D.C. jazz pianist Will Rast, at the Central Park SummerStage in New York City. RAMP member Sibel Thrasher died in April 2020.In 2008, the song "Daylight" featured Grand Theft Auto IV on the fictional radio station The Vibe 98.8.

    Hi, a newcomer here. I need to know the value(s) of the force(s) acting on each inclined face of a double ramp. Here's a visualisation of a double inclined ramp (just an example, could be asymmetric): Imagine a body rests on the top faces, let's assume it's a circular bar (a cylinder) which...

    Static vs Kinetic Friction on an Unbanked Ramp

    I used kinetic friction and did mgμ_k=mv^2/r. However, the solution is mgμ_s=mv^2/r. I am confused on why we consider static friction and not kinetic friction, thanks!

    I Distance traveled by a ball down a ramp and on a flat path

    Question: A ball is hit with a certain force and it starts with an initial velocity of V m/sec decelerating due to friction along a flat path and then up an inclined ramp coming to stop at the top of the ramp where the ramp becomes flat again (as per diagram A). The total distance traveled along...

    How does a mass moving up a ramp change its velocity?

    A point mass is moving at speed v, on a horizontal plane, until it reaches an incline. Immediately after just climbing up the incline, its speed remains at v, but its direction changes.

    Maximum force applied to prevent block from sliding up ramp

    A ball climbing a ramp while "rolling the wrong way"

    This image represents the ramp. The first part is pretty easy. The red part has friction, and the ball rolls down it. The blue part has no friction, and the ball climbs it only owing to the translational kinetic energy that it gained at the bottom of the red ramp, which is only a fraction of...

    When the mass starts sliding down, it will induce a current due to the cutting of B field.
