Centripetal Force | Physics - Lumen Learning

Modern roller coasters have vertical loops like the one shown in Figure 6. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats.

Window blind - Wikipedia

The most common window blinds are Persian blinds, which consist of many horizontal slats, usually of metal or vinyl, connected with string such that they can be rotated to allow light to pass between the slats, rotated up to about 170 degrees to hide the light, or pulled up so that the entire window is clear.. Venetian. A Venetian blind has horizontal slats, located one above another.

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 ...

Roller coaster - Wikipedia

A roller coaster, also called a rollercoaster, is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. People ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller ...

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.

1.5 Boundary Conditions | Learn About Structures

In two dimensions (2D), each free point on a structure has three different possible DOFs: one horizontal, one vertical, and one rotational. This means that a point can move (translate) in the x-direction and y-direction, or can rotate about the out-of-plane z-axis (equivalent to rotating within the 2D plane).

Types of Support in Structures - Mechanical Booster

The reaction offered by the roller support is shown in the figure given above. The roller supports are unable to resists the lateral loads (the lateral loads are the live loads whose main components are horizontal forces). They resist only vertical loads. The best example of roller support is the roller skates.
