Question

The 20-g centrifuge at NASA's Ames Research Center in Mountain View, California, is a cylindrical tube 58 ft long with a radius of 29 ft (see figure). If a rider sits in a chair at the end of one arm facing
the center, how many revolutions per minute would be required to create a horizontal normal force equal in magnitude to 20.0 times the rider's weight?

Helicopter blades withstand tremendous stresses. In addition to supporting the weight of the helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip. The tip of a 4.00 m long helicopter blade that rotates at 5 Hz. (a) What is the linear speed of the tip of the blade? (b) What is the centripetal acceleration at the tip? (c) How many g’s is this?
In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 15.0 m in diameter. It is found that the pilot blacks out when he is spun at 30.6 rpm (rev/min). At what acceleration (in SI units) does the pilot black out? acceleration: 77.01 m/s? Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.858 If you want to decrease the acceleration by 22.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? percent of time change:

High-speed ultracentrifuges are useful devices to sediment materials quickly or to separate materials. An ultracentrifuge spins a small tube in a circle of radius 10.5 cm at 60000.0 rev/min. What is the centripetal force experienced by a sample that has a mass of 0.00330 kg?

A 2.0kg ball swings in a vertical circle on the end of an 80cm long string. The tension in the string is 20N when its angle from the highest point on the circle, 0, is 30deg. a) What is the ball's speed when 0-30deg? b) What are the magnitude and direction of the ball's acceleration when 0=30deg?
Life scientists use ultracentrifuges to separate biological components or to remove molecules from suspension. Samples in a symmetric array of containers are spun rapidly about a central axis. The centrifugal acceleration they experience in their moving reference frame acts as "artificial gravity" to effect a rapid separation. If the sample containers are 11.9 cm from the rotation axis, what rotation frequency is required to produce an acceleration of 1.85-105 g? Submit Answer Tries 0/99
