Trigonometry - Working with linear and angular speed
When working with wheels its important to recognize that there is a connection between linear and angular speed. This video will show a few example on using the formula v = rw for finding either linear speed or angular speed. Near the end we also cover how to covert unit which is useful

THE MAKING(English Version) (314)The Making of Steel Balls
This edition of the series of programs explaining the technology used to produce items that are familiar in our daily life features ‘Steel Balls’. A bicycle wheel spins smoothly because the wheel axle contains ball bearings. The steel balls inside the ball bearing must be close to perfectl

Physics, Torque (6 of 13) Compound Wheel
Shows how to calculate the individual torques and net torque produced by forces applied to a compound wheel. Torque is a rotating force. It is a measure of how much force is acting on an object that causes the object to rotate. The object will rotate about an axis, which is called the piv

Francis BROWN - Graph Complexes, Invariant Differential Forms and Feynman integrals
Kontsevich introduced the graph complex GC2 in 1993 and raised the problem of determining its cohomology. This problem is of renewed importance following the recent work of Chan-Galatius-Payne, who related it to the cohomology of the moduli spaces Mg of curves of genus g. It is known by Wi

Spin Until You Lose - Probability Riddle
You spin a wheel and it randomly lands on $1, $2, or END. If you land on $1 or $2, you bank the money and spin the wheel again. You keep spinning until you land on END, at which point you cash out the money you banked. How much do you expect to win on average? What if the wheel has values
