The following figure shows a top view of a spinning, cylindrical gyroscope wheel. The pivot is at O, and the mass of the axle is negligible. Use ?=2.9cm and ?=3cm.  a. As seen from above, is the precession clockwise or counterclockwise?  b. If the gyroscope precesses at 1.7 revolution per second, what is the angular speed of the wheel in revolution per minute? Insert your answer correct up to at least a third decimal place.

a. Which term(s) in this equation is/are eliminated if Point A is stationary? b. Which term(s) in this equation is/are eliminated if Frame A rotates with constant angular velocity? c. Which term(s) in this equation is/are eliminated if Frame A is fixed to a rigid body and Point B is a point on that body? d. From a definition of position vector FB/I = TA/I + TB/A, derive the expression for acceleration below TA/I 144 A TB/1 TB/A B B/1 = A/I +B/A+A/I XTB/A+20A/I XUB/A+WA/IX (WA/IXTB/A)

The uniform rod of mass M and length L rotates in the plane of the figure about an axis through one end. As the rod swings through its lowest position, it collides with a putty wad of mass m, that sticks to the end of the rod. If the rod's angular speed just before collision is w, a) what is the angular speed of the rod-putty system immediately after collision? Rotation axis Rod b) What is the change in the kinetic energy of the rod-potty system (immediately before to immediately after the collision)? Does the kinetic energy increases, decreases, or remains the same? Provide your answers symbolically.

A wheel is attached by a cable to a block  The wheel has a radius of 2ft and weighs 300lbs, the block weights 20lbs. If the radius of gyration about the point of rotation of the disk is 1.5ft, how many revolutions will it take for the wheel to come to a stop assuming it was moving at 10 rad/s CW. Assume the block is on the left side of the wheel and thus causes a CCW moment.
