if you delvelope a object to spin around in a circle on a gyryoscope and on the spinning axis u put heavy objects in an evenly distributed space. causing the object to push forward if given a higher amount of wieght in one ball .. if in space this will throw the object towards a certain direction..

making it spin in such away that it throws the object foward..

Wheel A of radius rA = 10 cm is coupled by a belt B to wheel C of radius rC= 25 cm. The angular speed of wheel A is increased from rest at a constant rate of 1.6 rad/s^2. Find the time needed for wheel C to reach an angular speed of 100 rev/min, assuming the belt does not slip. (Hint: If the best does not slip, the linear speeds at the two rims must be equal.)

Please help me with this problem I really want to learn how to solve it because I have an exam next week and I don't understand this! Thanks so much!

A disk rotates about its central axis starting from rest and accelerates with constant rotational acceleration. At one time it is rotating at 10 rev/s; 60 revolutions later, its rotational speed is 15 rev/s. Calculate (a) the rotational acceleration, (b) the time required to complete the 60 revolutions, (c) the time required to reach the 10 rev/s rotational speed, and finally (d) the number of revolutions from rest until the time the disk reaches the 10 rev/s rotational speed. What equations would you use, and can you explain your answer?

a siren can be made by blowing a jet of air through twenty equally spaced holes in a rotating disk. the time it takes for successive holes to move past the air jet is the period of the sound. the siren is to produce a 2200 Hz tone. what must be the angular speed in rad/s of the disk? please give me step by step, not just the answer. thanks.

I need to know if the coefficient of friction will change if i change the load on a block. I believe that myu will not change unless you change the surface that the block slides on.

Do you believe that this is a valid answer?
Increasing the load will not change either coefficient of friction because the load doesn't effect the ratio of the force of friction to the normal force.
