A 10-kg disk-shaped flywheel of radius 9.0 cm rotates with a rotational speed of320 rad/s.
Part A. Determine the rotational momentum of the flywheel.
Part B. With what magnitude rotational speed must a 10-kg solid sphere of 9.0 cm radius rotate to have the same rotational momentum as the flywheel?

To appreciate the strength of gravity, calculate the number of steel cables that would be required in the absence of gravity to hold the moon in orbit about the earth.
A ball is thrown vertically upward on the moon and returns to its starting point after 4 sec. The acceleration on the moon is 1.6 m/s2. Find the balls original speed
Determine the tensile stress in each segment of the bar shown. Segment AB has a square cross section 2in by 2in. Segment BC has a circular cross section with a diameter of 1.75in. The tensile load P = 75 kips.
The concept of thermionic emission is the basis of modern X-ray tubes, which are the workhorse of a medical X-ray image. In this process a filament (a piece of metal in a vacuum) is heated by the application of electrical current
