Making average angular velocity help please!?
Hi, I'm a great difficulty in this, ive done A – D, but can not make final 2 E and F, any help / advice or links would be great! a steering wheel has a mass of 225 kilos and spins at 3,000 revolutions per minute on a pair of bearings 120 mm in diameter, with a coefficient of friction of 0.032. Calculate: A) The load on each bearing. B) The frictional force exerted on each bearing c) The work done per minute for overcome friction d) The total power consumed per minute in overcoming friction. The wheel takes 30 seconds to reach the specified angular velocity. Calculate e) average angular acceleration f) The linear distance of a point on the steering wheel travel at that time A) F = mg = 225 x 9.81 = 2207.25N 2207.25 / 2 = 1103.625N b) mg = mx (m = 0.032) = 0.032 x 1103.625 = 35.316N c) Work done = Force x Distance In a revolution – 35 x πD = π x 35.316 x 0.12 = 13.31 A 3000rpm = 3,000 x 13.31 = 39.941,45 N / md) = 39941.45/60 power 665.6pw
This seems easier than the work you've done already. I hope it's not something that makes them unconfirmed more difficult. E) means ACC ang = omega / t = 3000 rpm / 30 s = 100 rpm / s = 2 * pi * 100 rad / sf), and from the data, we do not know whether ACC is constant ang or not, we will assume that is constant. Also assume the point is located within a radius R s = 0.5 * ACC ang * t ^ 2 * R BTW, the units (c) nm N / m, and (e) suppose that "p" in PW is a typographical error.

The Man Who Deciphered Linear B $15.98 The decipherment of Linear B by Michael Ventris some fifty years ago is the equivalent in the humanities of Crick and Watson’s discovery of the structure of DNA. Today it belongs in the same rare class as Champollion’s decipherment of Egyptian hieroglyphs in the nineteenth century. The earliest European writing system that we can understand, Linear B dates from the middle of the second millennium BC. It was rediscovered by Sir Arthur Evans, the archaeologist who excavated clay tablets bearing this ancient script at Knossos in Crete in 1900. Obsessed with cracking Linear B, Evans kept the tablets to himself for some forty years but made little progress. After his death, other scholars tackled the decipherment, but it wasn’t until 1952 that the secret was penetrated. Linear B was not an unknown language such as Minoan or Etruscan but actually an archaic dialect of Greek, more than five hundred years older than the Greek of Homer. Michael Ventris’s later collaborator, the Cambridge classicist John Chadwick, told the story in his famous book, The Decipherment of Linear B (1958). But what of the man behind the decoding? Here Chadwick’s book is exceptionally reticent, because in truth he hardly knew Ventris. Based upon hundreds of unpublished letters and other sources, including Chadwick’s papers, Andrew Robinson’s biography is the first book to tell the story of both the decipherment of Linear B and the man who broke the code. His research reveals a most intriguing person: a dazzling polyglot with an unorthodox upbringing and socialist tendencies who was also extremely private and lacking in confidence, and who died in a mysterious car crash in 1956 at the age of thirty-four. Ventris trained successfully as an architect, and his design methods shaped his decipherment work. But it was his hobby, Linear B, that would make him immortal. 20 b/w illustrations. |
