The disk rotates with the angular motion shown. The peg at B is fixed to the disk. Suppose that w = 6 rad/s, a = 10 rad/s2, r=0.3 m, and a = 1.25 m. (Figure 1) Figure 1 of 1

I will rate your answer as soon as possible, thank you.

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.

2. Two rigid links are rotating in the horizontal plane as shown in the figure below. The left-most link rotates with angular rate ₁ of 4 rad/s. The end of the right-most link holds a pin which is confined to move along a slot in the other link. The length of the right-most link 72 is 0.45 m. Determine the angular rate ₂ of the second link at the instant shown. Use 0₁ = 30°, 0₂ = 60°, and r₁ = 0.6 m. 0

A wheel in fixed axis rotation spins at 300 rpm and decelerates at α = 3 rad/s2. How long does it take for the wheel to come to a complete stop?

The ends of rod AB (link 3) are pin connected to slider 2 at A and disk 4 at B. The disc is rolling without sliding on horizontal surface. At the instant when 0 = 50°, the speed of A is VA = 3.5 m/s directed to the right. a) Locate, on the figure, the I. C. R. for the rod AB and for the disk. b) Use the respective I. C.
