A uniform solid cylinder of mass M is supported on a ramp that rises at an angle θ above the horizontal by a wire that is wrapped around its rim and pulls on it tangentially parallel to the ramp part A: Explain why there must be friction on the surface for the cylinder to balance this way. part B: Explain why the tension in the wire must be equal to the friction force.Mastering Physics System Requirements | Pearson
We are now in a position to understand certain musical terms from a physics perspective. The standing wave frequencies for this string are , , , etc. This set of frequencies is called a harmonic series and it contains common musical intervals such as the octave (in which the ratio of frequencies of the two notes is 2:1) and the perfect fifth (in which the ratio of frequencies of the two notes ...Mastering Physics Problem 21.20? | Yahoo Answers
The Young's modulus of each wire is . The wires are slightly twisted together, so that the resultant wire has length and is ten times as thick as the individual wire. What is the Young's modulus of the resulting wire? ANSWER: By rearranging the wires, we create a new object with new mechanical properties. However, Young's modulus depends on the material, which remains unchanged. To change the ...UMD Department of Physics - UMD Physics
