Question

You have a horizontal grindstone (a disk) that is 94 kg, has a 0.32 m radius,
F
is turning at 89 rpm (in the positive direction), and you press a steel axe against the edge with
a force of 22 N in the radial direction.
Randomized Variablesm = 94 kg
r= 0.32 m
f= 89 rpm
F = 22 N
Assuming that the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of
the grindstone in rad/s?.

You have a horizontal grindstone (a disk) that is 87 kg, has a 0.31 m radius, is turning at 94 rpm (in the positive direction), and you press a steel axe against the edge with a force of 23 N in the radial direction. The kinetic coefficient of friction between steel and stone is 0.20. What is the number of turns, N, that the stone will make before coming to rest?
A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.7s before coming to rest.How many revolutions did the centrifuge complete after being turned off?Δθ= (?) rev
A potter's wheel, with rotational inertia 12 kg-m², is spinning freely at 40 rpm. The potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. If the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay? 1.4 kg 2.3 kg 1.8 kg O 2.1 kg
A van with mass m = 1000 kg is driving around a circular curve of radius r = 950 m when it begins to rain. The coefficients of static friction between the track and tires is μd = 0.59 when dry and μw = 0.17 when wet. Write an expression for the maximum magnitude of the force of static friction Ff acting on the van if μs is the coefficient of friction. What is the maximum tangential speed that the van can take the corner at without slipping when dry in m/s? What is the maximum tangential speed when wet in m/s?
16. FHS science department has centrifuges that operate at 3400 rpm. A particle at the bottom of a test tube in this centrifuge is 10 cm away from the axis of rotation. From the reference frame of the test tube the particles in the tube experience a centrifugal force equal to some multiple of their weight (i.e. a certain number of “g”s). Determine the centrifugal force of these centrifuges in g’s.
The shaft of an elevator motor turns clockwise at 180 rpm for 10 s, is at rest for 15 s, then turns counterclockwise at 240 rpm for 12.5 s. What is the angular displacement of the shaft during this motion? Draw angular position and angular velocity graphs for the shaft’s motion
The power required to rotate an object and overcome friction is P = –bw, where w is the angular speed of the object. What are the SI units of b? kg · m/s kg · m? /s kg · m2 /s S kg · m? kg /s none of these
A rotating space station is said to create "artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. The outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. Randomized Variables d = 180 m If the space station is 180 m in diameter, what angular velocity would produce an "artificial gravity" of 9.80 m/s² at the rim? Give your answer in rad/s.
A disc is rolling on the ground and moving at 30 m/s as a result of its rolling. The disc stops in 20 s after an external force acts on it. How many turns will it make before it stops? Also find the amount of torque that was applied on the disc that stopped it from rolling. The mass of the disc is 50 kg. R = 40 cm V = 30 m/s
