Vertical Circles - Eastern Illinois University

Top of a Hill. The only forces acting on the rider are the upward normal force n exerted by the car and the downward force of gravity w, the rider's weight.These add together, as vectors, to provide the net force F net which is the centripetal force F c, directed toward the center of the circle. The normal force may also be called the rider's "apparent weight" for this is the force of the seat ...

Mathematically Designing a Frictional Roller Coaster ...

A roller coaster's initial height and slope determines its length. The higher the initial point, the longer the path. It is best that the initial roller coaster slope not be steeper than ±2.5, otherwise the marble may slide instead of roll. This guideline is an outcome from testing different initial slopes.

Side shuffle and side lunge. Two other common movements that are classified in the frontal plane are the side shuffle and side lunge. Both exist predominantly in one plane. Even though the knees, ankles, and hips flex and extend during the exercises, the primary movement is the entire body tracking side-to-side with the frontal plane, creating sheer (sideways) forces on the body.

6 Key Differences of Vertical & Horizontal Motors | Pumps ...

Vertical motors with spherical roller bearings are not designed to run without an adequate amount of down thrust to preload the bearing and keep the rollers from skidding. If the motor runs disconnected from the pump, the rollers may skid and damage the bearing. Check with the manufacturer for instructions before running the motor uncoupled for ...
