Study Notes
Problem 9
- Passengers ride the 'Corkscrew' amusement ride which travels through a cylindrical helix
- The velocity at position A is 15 m/s
- The cylindrical helix has an effective radius of 5 meters
- The helix angle is 40 degrees
- The acceleration of the passengers at point A is 27.5 m/s^2
- This problem is related to space curvilinear motion, in particular, cylindrical coordinates
Problem 10
- An airplane flies through a vertical loop in the x-y plane
- The airplane's speed at the bottom of the loop is 600 km/h
- The loop has a radius of curvature of 1200 meters
- The rate of change of the radius (( \dot{R} )) is 34.4 m/s^2
- The angular acceleration (( \ddot{\theta} )) of the plane at the bottom of the loop is 0.01038 rad/s^2
- This problem is related to space curvilinear motion, in particular, spherical coordinates
Problem 11
- A spacecraft ( S ) approaches Mars along a trajectory
- The spacecraft's velocity is 19 km/s
- Mars' velocity is 24.1 km/s
- The angle between the spacecraft's trajectory and Mars' orbital plane is 15 degrees
- ( \beta ) is the angle between the line of sight ( S-M ) and the spacecraft's trajectory ( b-b )
- ( \beta ) is calculated to be 55.6 degrees.
- This problem is related to relative motion
Problem 12
- Block B accelerates to the right at a constant rate of 3 m/s^2 due to a force ( P )
- Block B's velocity is 2 m/s to the right
- Block B's acceleration is 0.5 m/s^2
- Block A's acceleration is 0.75 m/s^2
- The absolute velocity of point C is 1 m/s to the right
- The velocity of Block B relative to Block A ( v_{B/A} ) is 0.5 m/s
- This problem is about the constrained motion of connected particles
